Mar 31, 2014 GRB 140330A: intense and persistent gamma-ray emission detected by AGILE.
New GCN issued: GCN #16058 (C. Pittori et al.)

Following the IPN triangulation of GRB 140330A (GCN #16051) and subsequent gamma-ray data analysis, the high-energy source detected by Fermi (GCN #16048) and by AGILE (GCN #16058) was found to be unrelated to GRB 140330A, and it has been tentatively associated with the extra-galactic radio source PKS 2136-642, as reported in GCN #16062.

Feb 12, 2014 AGILE gamma-ray detection of a new unidentified source in 2010 has led to the discovery of the first ever known Be-BH binary system.
On July 2010 the ASI AGILE gamma-ray satellite recorded an intense and sporadic gamma-ray emission above 100 MeV from a new unidentified source, AGL J2241+4454 (Lucarelli F. et al., ATel #2761).

MWC 656 (also known as HD 215227) is a rapidly spinning Be-type star located within the error circle of the AGL J2241+4454 gamma-ray source, which was identified as its candidate optical counterpart, and proposed as a new member of the small class of gamma-ray emitting binaries (Williams S. J. et al., ApJ 723, 2010).

A recent detailed analysis of the optical spectrum of MWC 656 allowed researchers to infer the characteristics of its companion, that turned out to be an object with a mass between 3.8 and 6.9 solar masses. Such a compact object can only be a black hole, as no neutron star with more than about three solar masses can exist according to current theoretical and observational studies.

This important discovery was recently published in Nature by a group of Spanish scientists (Casares J. et al., Nature 505, 2014). Two of them, Marc Ribò and Josep M. Paredes, members of the Group High Energy Astrophysics at Universitat de Barcelona, have also been AGILE Guest Observers in past ASI Announcements of Opportunity.

Jan 15, 2014 AGILE scientific operations in stand-by since Jan 1st, 2014

Apr 30, 2013 GRB 130427A: high energy gamma-ray detection by AGILE and Fermi
AGILE detected high energy emission above 50 MeV with the Gamma-Ray Imaging Detector (GRID) and above 350 keV with the Mini-Calorimeter MCAL) from the long-duration GRB 130427A on April 27, localised by Swift (GCN 14448, Maselli et al.).
Due to the exceptionally high fluence above 100 MeV of this burst, it was possible for the first time to derive its properties using the technique ("maximum likelihood") routinely used in the standard data analysis of AGILE-GRID point sources.

This burst was detected above 100 MeV and reported previously by the Fermi Large Area Telescope (LAT).
The LAT data show a multi-peaked light curve consistent with the Fermi GBM trigger. More than 200 photons above 100 MeV are observed within 100 seconds with a TS above 1000.

Different observations by other space missions such as MAXI, INTEGRAL and Konus-Wind and by optical/NIR and radio ground-based telescopes followed.

November 24, 2011 AGILE sheds light on the mistery of the origin of comic rays
AGILE has discovered a pattern of gamma-ray emission from the supernova remnant W44 that, combined with the observed multifrequency properties of the source, can be unambiguously attributed to accelerated protons interacting with nearby dense gas.

The AGILE gamma-ray imager reaches its optimal sensitivity just at the energies in the 50 MeV-a few GeV range at which neutral pions (produced by proton-proton interactions) radiate with an unambiguous signature.

The AGILE data resolves the problem of clearly identifying a source of energetic cosmic rays in our Galaxy exactly 100 years after the discovery of cosmic rays by Victor Hess in 1912. Up to now a direct identification of sites in our Galaxy where proton acceleration takes place was elusive. This important AGILE result is reported in a paper to be published by Astrophysical Journal Letters (A. Giuliani et al., 2011).

All the scientific oriented activities related to the analysis, archiving and distribution of AGILE data are supported by the AGILE Data Center at ASDC.

November 9, 2011 AGILE Cycle-3 Public Data Now Available
The proprietary period for the AGILE Cycle-3 Observation Blocks (OB) from OB 8600 to OB 10400 has currently expired. The data are public and available from the ASDC Multimission Archive (MMIA) webpage for the AGILE Mission.

Since the beginning of Cycle-3 the AGILE satellite is operating in a spinning observing mode, i.e. with the instrument axis sweeping the sky with an angular speed of ~0.8 degree/sec. The allowed pointing directions lie on a great circle orthogonal to the Sun direction, whose orientation changes with time, so that the whole sky is accessible during a six months period.

The new public GRID data are related to the first 19 AGILE observations of Cycle-3, from 2009-10-31 to 2010-10-15. These data have been processed with the latest available software and calibrations optimized for the new observing mode.
The new public AGILE archive is now containing both Cycle-3 spinning, and Cycle-1 and Cycle-2 pointing data.

The query to the archive give access to the public data, producing an interactive table including the ASDC "On-line Analysis" tool.


********** Imaging tool at ASDC **********
The ASDC interactive tool allows web users to preview the AGILE public data fields and to perform a preliminary analysis around a chosen sky position. The tool uses the XIMAGE software package for multi-mission X-ray astronomy, adapted to gamma-ray image display and data analysis.

December 21, 2010 Reprocessed AGILE Cycle-1 and Cycle-2 Public Data Now Available
A new version of the whole AGILE archive for all Cycle-1 and Cycle-2 data, reprocessed with the latest available software (sw=5_19_18_17) is now available, including data of the last two AGILE Cycle-2 Observation Blocks (OB8300 and OB8400) whose proprietary period expired today.

This is the same software version used for the creation of the proprietary Cycle-3 data delivered to successful proponents of the AO3 AGILE Guest Observer Program.

During Cycle-1 and Cycle-2 AGILE was operated by performing long observations, called Observation Blocks (OBs), typically of 2-4 weeks duration. On November 4, 2009, toward the end of Cycle-2, AGILE scientific operations were reconfigured following a malfunction of the rotation wheel occurred in mid October,2009. The satellite is currently operating regularly in a spinning observing mode, surveying a large fraction of the sky each day.

As in previous public deliveries, AGILE public data in pointing observing mode have been cleaned by eliminating time periods corresponding to repointing slews and occasional losses of fine-pointing attitude.

Moreover the present data release also includes non-cleaned data, treated in a similar way to those presently taken in spinning observing mode.
WARNING: to avoid spurious artefacts, this set of non-cleaned data must be carefully analysed using a smaller field of view (fovrad=50).

The new public data are available from the ASDC Multimission Archive webpage for the AGILE Mission. Data delivery details can be found in the AGILE_data_release_note_v5.0 (txt, pdf)

October 7, 2010 The Crab "goes wild" in gamma-rays
More suprises from sky observations in gamma-rays.
The ASI satellite AGILE, thanks to its sky monitoring capability and fast ground segment alert system, has discovered an increased gamma-ray flux above 100 MeV from a source positionally consistent with the Crab Nebula.

The unexpected discovery has been promptly reported on September 23, 2010 in ATel #2855 (M. Tavani et al.), and confirmed the next day by the Fermi satellite in ATel #2861 (R. Buehler et al.). Fermi interrupted its all-sky scanning mode and completed a dedicated pointed observation of the Crab Nebula from 2010-09-23 to 2010-09-27 to increase its exposure on the source. Measurements taken starting on 23 September show that the gamma-ray flux is back to normal values, see ATel #2879.

The Crab Pulsar and Nebula are the remnants of the explosion of the supernova SN1054, and the spectra containing the diffuse and pulsed emission has always been considered the standard X-ray candle for X-ray and gamma-ray satellites used also for instrument calibration.

Following the surprising discovery by AGILE, the results of INTEGRAL observations of the Crab nebula, performed for calibration purpose, and the Swift/BAT team routine monitor of the source were reported in ATel #2856 and ATel #2858 respectively. In these hard X-rays observations, however, no statistically significant increase in the Crab flux was observed.

Special ToO observations were then requested and performed by Swift, see ATel #2866, Chandra, see ATel #2882, and Hubble Space Telescope, see ATel #2903. Comparing the current Crab Nebula image with the extensive database available in the HST public archive, an increased emission about 3 arcsec East of the pulsar was noticed. The Chandra exposure, taken a few days before the HST one, reported a brightening from the same region.

Gamma-ray data suggests that the origin of the flare is related to the nebula rather than the pulsar emission, and provide evidence for particle acceleration mechanisms in nebular shock regions more efficient than previously expected from current theoretical models.


In the image background: Chandra X-ray Observatory data from the ToO observation of Crab on September 28, 2010, following the gamma-ray flare detected by AGILE.

February 15, 2010 The AGILE satellite detects "super-energetic TGFs" that could affect air travel
"Terrestrial Gamma-Ray Flashes" (TGF) are phenomena of terrestrial (atmospheric) origin only lasting a few milliseconds that are likely associated to very intense tropical thunderstorms. The AGILE satellites detected several of these events since its first months of operations.

The AGILE equatorial orbit, together with its advanced payload capabilities, allowed the discovery of TGFs with gamma-ray energy reaching up to 50 MeV.
Such highly energetic radiation must be produced in atmospheric conditions requiring potential differences of 100 Mega Volts or more, hundreds of times larger than that required to produce the usual terrestrial lightning.

As announced in a joint press release that can be found on the ASI and INAF websites, the AGILE Team and ASI are collaborating with ENAC (Ente Nazionale per l'Aviazione Civile) to understand the possible hazards to air traffic that these very energetic atmospheric events might cause.

THE AGILE paper "Detection of Terrestrial Gamma-Ray Flashes up to 40 MeV by the AGILE satellite" by M. Marisaldi et al. (2009), previously announced on this website on October 29th 2009, is now being published in the Journal of Geophysical research and it is accessible on-line at:

December 3, 2009 AGILE detects an extraordinary gamma-ray activity from the FSRQ 3C 454.3
New ATel issued: ATel #2326 (E. Striani et al.).
The AGILE Gamma-Ray Imaging Detector (GRID) has been detecting an extraordinary intense gamma-ray emission above 100 MeV from the flat spectrum radio quasar 3C 454.3. The AGILE quick-look analysis yields a source flux of about (1800 +/- 400)e-8 ph/cm2/sec (E > 100 MeV). This flux value greatly exceeds the value reported by AGILE yesterday in ATel #2322 (E. Striani et al.), showing a rapid increase (about 80%) of the gamma-ray flux of 3C 454.3 in the last 24 hours. See ATel #2326 for further details.

The paper "Discovery of extreme particle acceleration in the microquasar Cygnus X-3", by M. Tavani et al., 2009, to appear in Nature (see also arXiv:0910.5344), reports on the AGILE detection of gamma-ray flaring emission from the microquasar Cygnus X-3, which tends to occur before the onset of powerful relativistic radio jets.

November 12, 2009 AGILE science operations resumed on November 4th, 2009
On November 4, 2009 at 12:25:54 the AGILE scientific operations restarted. The instrument is operating nominally, and all detectors are on and acquiring data. The satellite is currently in a safe spinning mode, with the fixed solar panels pointing towards the Sun and the GRID instrument FOV covering a good fraction of the whole sky.
In the figure below we show a preliminary 100-orbit gamma-ray intensity map above 100 MeV in the spinning configuration.



October 29, 2009 AGILE paper on Terrestrial Gamma-Ray Flashes now available
The AGILE paper: "Detection of Terrestrial Gamma-Ray Flashes up to 40 MeV by the AGILE satellite", M. Marisaldi et al. 2009, is now accessible on-line here. The paper was accepted for publication in the Journal of Geophysical Research. Copyright 2009 American Geophysical Union. Further reproduction or electronic distribution is not permitted.

October 23, 2009 AGILE science operations interrupted
On Sunday, October 18th 2009, one of the subsystems on board the AGILE S/C suffered a malfunction that caused the satellite to leave its nominal pointing mode and switch to the "spinning" control mode. The "spinning" control mode guarantees the safety of the Spacecraft and of the Payload.
Analysis is in progress in order to assess the status of the satellite and the possibility to restart operations as soon as possible.

October 15, 2009 AGILE detection of the gamma-ray blazar PKS 1830-211
New ATel issued: ATel #2242 (E. Striani et al.)

October 14, 2009 New AGILE public software package and test dataset available
We are pleased to inform you that a new software package for AGILE-GRID data analysis is now available from the AGILE Data Center webpage http://agile.asdc.asi.it/public/AGILE_SW_4.0_SourceCode/

The software is available both for AGILE Guest Observers and for general public users. The new AGILE software package BUILD_GRID_4.0.tgz is delivered together with a test dataset, test_dataset_4.0.tgz, and it is intended for the scientific software environment setup and testing.
Warning: Since the newly delivered spacecraft auxiliary (LOG) files have a very accurate time resolution (100 msec), several GB of available disk space are needed for AGILE data analysis.

The GRID analysis software is continuously evolving and regularly updated by the AGILE instrument Team and delivered to the AGILE Data Center (ADC) located in Frascati at the ASI Science Data Center for further testing, standardisation and integration into the ADC data analysis system.

This public delivery reflects the current best understanding and testing of calibrations, background rejection, and processing results.

October 14, 2009 Reprocessed AGILE Public Data Now Avalaible
The AGILE-GRID public data release (v2.0) is now available from the ASDC Multi Mission Interactive Archive webpage: http://www.asdc.asi.it/mmia/ which can be also reached from the AGILE home page: http://agile.asdc.asi.it by clicking: Public --> Data Release

The current set of public GRID data corresponds to the first 20 AGILE observations of Cycle-1, from December 1, 2007 to June 30, 2008.

Plese note that all Cycle-1 OB data already included in previous deliveries have been reprocessed with the latest available software.

MAIN IMPROVEMENTS:
- Event filters:
in previous data delivery a conservative event filter (F4) was used, optimized to select gamma-ray events within the central Field of View zone (< 40 deg radius) at the expenses of the effective area. The new standard AGILE event filter (FM) is optimized up to 60 deg off-axis.

- Spacecraft auxiliary (LOG) files:
the newly delivered auxiliary LOG files have a very accurate time resolution (100 msec)


This new public delivery reflects the current best understanding and testing of calibrations, background rejection, and processing results.
The previous public data release (v1.0) is still available from the MMIA AGILE webpage by selecting: Old Processing Archive.

Data delivery details can be found in the AGILE_data_release_note_v2.0 (txt, pdf)

As announced on April 1, a Scientific Mini-Workshop: "AGILE: 2 years after" will be held in Milano on 22-23 April, 2009 in coincidence with the second anniversary of the launch of the AGILE Mission.

Preliminary program and other useful information are now available at the 6th AGILE Workshop web site: http://agile.asdc.asi.it/workshop2009.html

April 2, 2009 AGILE Gamma-ray detection of GRB 090401B
The gamma ray burst 090401B (GCN #9066 and #9067, Schady et al. ) occurred in the field of view of AGILE, approximately 41 deg off-axis.
A description of the AGILE detection of the burst can be found in GCN #9069 (E. Moretti et al.).

A refined analysis of the AGILE-GRID (Gamma-Ray Imaging Detector) data of GRB 090401B confirms the gamma-ray detection of the GRB at energies above 30 MeV with a statistical significance larger than 4 for a 10-second integration after trigger, as reported in GCN #9075 (A. Giuliani et a.)

April 1, 2009 AGILE satellite: 10.000th pass over the ASI Malindi Ground Station
On March 31, 2009 at 21:53:38 UTC the AGILE satellite successfully completed its 10.000th pass over the ASI Malindi Ground Station.
All satellite subsystems and scientific detectors are working nominally after almost 2 years after launch. This very positive result is obtained thanks to the efficient collaboration of all involved Agilists, ASI, INAF, INFN and CIFS scientists, industry colleagues and technical operators.

April 1, 2009 AGILE: 2 years after (6th AGILE Workshop)

New ATel issued ATel #1976 (S. Vercellone et al.)

March 13, 2009 AGILE detection of a bright and persistent gamma-ray flare from the blazar PKS 1510-089
During the current AGILE pointing centered near the Galactic Center, the AGILE satellite has detected significant gamma-ray emission above 100 MeV from the source 1AGL J1511-0809 of the First AGILE Catalogue identified with blazar PKS 1510-08, see ATel #1968 (Pucella et al.) and ATel #1957 (F. D'Ammando et al.). The analysis of the most recent AGILE-GRID data integrated from 2009-03-12 06:57 UT to 2009-03-13 05:03 UT for photon energies above 100 MeV, gives a detection significance of above 9 sigma for a source flux in excess of 400 x 10^-8 ph cm^-2 s^-1.

May 15, 2008 GRB 080514B: SuperAGILE/IPN GRB Localization and possible AGILE detection at E>50 MeV
SuperAGILE and AGILE/MCAL detected a gamma ray burst on May 14th, at 09:55:56 UT. The event was localized by SuperAGILE at approximately 38 degrees off axis, in the one-dimensional portion of its field of view. The event was also detected by the burst detector onboard Mars-Odyssey, thus the IPN was able to reduce the SuperAGILE error box to the 100 sq arcmin error box, whose centroid is at (RA, Dec)= (322.820, 0.737).
The error box corners are given by the following coordinates (RA, Dec):

322.962 (21h 31m 50.81s) 0.733 (0d 43m 59.69s)
322.774 (21h 31m 5.74s) 0.667 (0d 40m 2.78s)
322.867 (21h 31m 27.99s) 0.806 (0d 48m 21.16s)
322.678 (21h 30m 42.80s) 0.740 (0d 44m 23.63s)

A description of the burst can be found in GCN 7715 (M. Rapisarda et al.)


As reported in GCN 7716 (A. Giuliani et al.) a quick look analysis of the AGILE GRID data of GRB 080514B shows a possible detection at energies E>50 MeV at a position consistent with the SuperAGILE-IPN localization .

May 9, 2008 GRB 080507: GRB localization by SuperAGILE
SuperAGILE detected and localized a gamma ray burst on May 7th, at 07:45:00 UT.

The burst position was reconstructed as (RA, Dec) (233.721 deg, 56.424 deg), which is:

RA(J2000) = 15h 34m 53.11s
Dec(J2000) = 56d 25' 27.3"

with an uncertainty of 3' radius. The given uncertainty accounts for both the statistical and systematic errors.

A description of the burst can be found in GCN 7697 (I. Lapshov et al.)

The event was detected during the passage of the AGILE spacecraft through the South Atlantic Anomaly.
The telemetry of the AGILE Gamma Ray Imager (GRID) is disabled during the passage through the South Atlantic Anomaly, thus no GRID data are available for this GRB.

April 29, 2008 Swift detection of the brightest X-ray flare from S50716+714
On 28 April 2008 Swift detected the blazar S50716+714 at X-ray and UV flux levels significantly larger than ever observed before. An analysis of the XRT data gives a 0.3-10 keV X-ray flux of 4e-11 erg/cm2/s, about 50% larger than that observed at the peak of the giant X-ray flare of October-November 2007.
Swift will continue the monitoring of S50716+714 over the next few days, while the AGILE Gamma-ray observatory will include this source within its field of view between April 30 and May 10, 2008. Multi-frequency observations are strongly encouraged (ATel.#1495, Giommi et al.)

April 29, 2008 AGILE gamma-ray detection of a variable source in the Cygnus region
The AGILE satellite, from data obtained between 2008-04-27 01:39 UT and 2008-04-28 01:27 UT, detected significant and variable gamma-ray emission from a source positionally consistent with 3EG J2020+4017, see ATel #1492 (F. Longo et al.).

Multiwavelength observations of the source location are strongly encouraged.

April 22, 2008 5th Science AGILE Workshop
We are pleased to announce the 5th Science AGILE Workshop "AGILE first year of gamma-ray astrophysics" to be held on June 12-13, 2008 at ASI-ASDC c/o ESA/ESRIN, Frascati .

April 10, 2008 GRB 080408: GRB Localization by SuperAGILE
SuperAGILE detected and localized a gamma ray burst on April 8th, at 18:12:48 UT. The event was approximately 13 degrees off-axis.
The burst position was reconstructed as (RA, Dec) (114.678 deg, 33.305 deg), which is:

RA(J2000) = 114.678 deg = 07h 38m 42.68s
Dec(J2000) = 33.305 deg = 33d 18' 16.7"

with an uncertainty of 3' radius. The given uncertainty accounts for both the statistical and systematic errors.

A description of the burst can be found in GCN 7571 (P. Soffitta et al.)

A preliminary analysis of the AGILE GRID data (E>100 MeV) does not show any significant gamma ray emission at the time and coordinates of the burst GRB 080408 localized by SuperAGILE, see GCN 7572 (S. Mereghetti et al.)

Swift performed a Target of Opportunity Observation of the SuperAGILE GRB 080408, starting ~25 ks after the trigger.
The results of XRT and UVOT data analysis in this field have been reported in GCN 7576, GCN 7577.

A GROND (La Silla Observatory, Chile) detection of optical/NIR afterglow candidate is reported in GCN 7581.

March 27, 2008 SuperAGILE detects an X-ray burst from a position consistent with IGR J17473-2721
The burst was detected on 26 March 2008, 23:19:40 UT, lasted approximately 40 s and it was significantly detected only in the energy range 17-25 keV, see ATel #1445 (E. Del Monte et al.).
Considering the intensity, the temporal and spectral properties of the event as well as the spatial coincidence with the source IGR J17473-2721 near the Galactic Center, we propose that the burst observed by SuperAGILE was indeed a Type I X-ray burst, and suggest that IGR J17473-2721 is an X-ray burster.
The SuperAGILE X-ray burst image and light curve are visible here .

November 6, 2007 GRB 071104: Gamma Ray Burst Localization by SuperAGILE
SuperAGILE detected and localized a gamma ray burst on November 4th, at 11:41:09 UT (*).
The event was approximately 22 degrees off-axis.
The burst position was reconstructed as:

RA(J2000) = 295.600 deg = 19h 42m 23.9s
Dec(J2000) = 14.645 deg = +14d 38' 42"

with an uncertainty of 8' radius. The given uncertainty accounts for both the statistical and systematic errors.

An analysis of the AGILE Gamma Ray Imager (GRID) data is in progress.
The Minicalorimeter also detected the event up to the energy range 0.7-1.4 MeV.

A description of the burst be found in GCN 7042 (Donnarumma et al.)

Swift started observing the field of view of the SuperAGILE burst GRB 071104 about 20.6 ks after the AGILE trigger.
The results of XRT and UVOT data analysis in this field have been reported in GCN 7043, GCN 7045 and GCN 7044

September 24, 2007 AGILE detection of a gamma-ray source possibly associated with Blazar TXS 0716+714 / S5 0716+71
The AGILE satellite, currently in its science performance verification phase, during the Observing Block that started on 2007-09-04 12:00 UT, detected significant gamma-ray emission from a source possibly associated with blazar TXS 0716+714 (other name S5 0716+714). See ATel #1221 (A. Giuliani et al.) for details.

Today, September 24, 2007 the GLAST-AGILE Support Program (GASP) of the Whole Earth Blazar Telescope (WEBT) reports on the observation of an optical flare of this blazar in the same period, see ATel #1223 (D. Carosati et al.).

September 14, 2007 AGILE AO-1 postponed

September 3, 2007 AGILE detection of a gamma-ray source off the Galactic Plane
The AGILE satellite, currently in its science performance verification phase, during an observation centered near the Galactic plane (l=334.44, b=10.06) that started on 2007-08-27 12:00 UT, detected significant gamma-ray emission from a source at approximately 33 degrees off the AGILE pointing direction, see ATel #1199 (Bulgarelli et. al).

August 31, 2007 SuperAGILE detection of GRB070824
On August 24th 2007, at 20:50:09 UT the SuperAGILE GRB-search ground software was triggered by GRB070824. The GRB was seen as a 3 second event, preceded by a weaker 2 s precursor 5 s earlier, leading to an overall burst duration of about ~10 s (T90=9.5 s), see light curve below (courtesy of I. Donnarumma, E. Del Monte, F. Lazzarotto, M. Feroci of AGILE Team).

The GRB was observed by SuperAGILE at 48.1 deg off-axis, a region of the instrument field of view with only one-dimensional imaging.

In addition, its arrival direction was partially obscured by the Earth's atmosphere. For these reasons, the SuperAGILE-only error box is a long, narrow strip limited by the instrument field of view and Earth occultation in one direction and by the imaging uncertainty in the other.

This event was independently detected by other IPN experiments, namely Konus-Wind, Swift/BAT, RHESSI,AGILE/Minicalorimeter, and the AGILE/Anticoincidence, as well as by Konus-A (Cosmos-2421). Their detection combined to provide further constraints to the burst localization to a triangular region, as shown in the figure below (courtesy of Valentin Pal'shin, Ioffe Physico-Technical Institute).

A detailed description of the burst and the localization area can be found in GCN 6767 (I. Donnarumma et al.)

August 7, 2007 AGILE detection of the blazar 3c454.3 in a high state
The AGILE satellite, currently in the science performance verification phase, has observed the 3C 454.3 field starting on 2007-07-24 14:30 UT, and ending on 2007-07-30 11:40 UT following the significant flaring activity of this blazar recently detected in the optical and X-ray energy bands.

Considering that the AGILE in-flight calibration is still ongoing, a gamma-ray source positionally consistent with 3C 454.3 was detected by the AGILE GRID (Gamma-Ray Imaging Detector), see ATel #1160 (S. Vercellone et al.) and ATel #1167 (A. Bulgarelli et al.).

The images below show the AGILE detection of the source in the gamma-ray energy band E > 100 MeV. The left picture is a detector image with superimposed a grid of Galactic coordinates in ARC projection. The right picture shows the same gamma-ray image distorted to match the Hammer-Aitoff projection in Galactic coordinates.

The experiment is not yet in its optimal configuration and in particular, the onboard triggering and imaging is not active yet and the absolute position reconstruction is being calibrated by using celestial X-ray sources.
Ground analysis results showed that the event was observed at 21 degrees off-axis and the observed duration in the 20-60 keV energy range is about 55 seconds, with a multi-peak time structure (see figures).

The burst position was reconstructed as (RA, Dec) (17.629 deg,57.673 deg), which is:

RA(J2000) = 01h 10m 31.0s
Dec(J2000) = +57d 40' 23"

with an uncertainty of 20' radius. The given uncertainty is almost entirely systematic and it is due to the very preliminary absolute position calibration, carried out only on 3 X-ray sources. At this preliminary stage the absolute positioning was obtained by the ground calibrations, preliminarily checked with these sources. The error box may be improved over the next hours/days.

An analysis of the AGILE Gamma Ray Imager (GRID) data is in progress. A quick look analysis does not show any bright gamma-ray transient in coincidence with the X-ray emission of GRB 070724b.
These results have been published in GCN 6668 (Feroci et al.) http://gcn.gsfc.nasa.gov/gcn3/6668.gcn3

Following the SuperAGILE trigger the field of GRB070724b was observed by SWIFT leading to the observation of 2 probable X-ray afterglow candidates (Romano et al., GCN 6669).

July 26, 2007 AGILE Observations of 3C454.3
On July 24, 2007 AGILE Observations of 3C454.3 the AGILE satellite carried out a re-pointing of the 3C454.3 field starting on July 24, 2007, 4:30pm, following the significant flaring activity of this blazar that was recently detected in the optical and X-ray energy bands. The pointing centroid coordinates of the co-aligned AGILE gamma-ray and X-ray imagers are:
R.A. (J2000) = 17.829
DEC. (J2000) = 36.694

(l= 127.364, b = -26.007).

The 3C 454.3 source turns out to be positioned about 36 degrees off-axis with respect to the AGILE pointing centroid. The AGILE gamma-ray imager detection capability at that off-axis position is nominal.

AGILE will point at the 3C 454.3 field for the time period:
start: July 24, 2007, 4.30 pm
end: July 30, 2007, 12:00am.

Multifrequency observations of the source are encouraged. Please contact

On July the 2nd and 3rd it has been hold at ASDC site the italian Workshop dedicated to gamma-ray astrophysics from space, focused on AGILE and GLAST missions.

The conference was attended by 140 people from the astrophysics and particle physics communities, industrial entities and the President of ASI, INFN and INAF.

During the Workshop the First AO for AGILE Mission was prsented. Some first very promising results were presented, some of which have been announched in other News.

Results from the GLAST on-ground calibration have been presented as well as the Science Working Group activity in preparation to the launch, now foreseen in January 2008.

Part of the Workshop was dedicated to the sinergies with other observatories and telescopes, such as INTEGRAL, Swift, MAGIC etc.


July 6, 2007 AGILE: SuperAGILE first light
As announced previously, the hard X-ray imager SuperAGILE clearly detected a flare from the source GX301-2 as its first light. These images (courtesy of E. Del Monte, I. Donnarumma, Y. Evangelista, F. Lazzarotto, L. Pacciani of Agile Team) are the results of an immediate raw and very preliminary deconvolution of two detectors. Analysis of the data with the scientific software is in progress. Preliminary results show a declining of the source flux over the subsequent orbits.

July 4, 2007 AGILE: 1,000 orbits and approaching the end of the Commissioning phase
AGILE has completed yesterday its 1,000th orbit and has almost come to the completion of the initial start-up/Commissioning phase.

On July 2nd, at the ASDC/ESRIN Workshop on Gamma-ray Astrophysics in Italy, several AGILE preliminary results have been presented. In particular:

- The hard X-ray imager SuperAGILE clearly detected a flare of the source GX301-2 as its first light.

- A gamma-ray burst was detected by all active detectors on June 22. The burst position turned out to be about 80 degrees off-axis.

- The AGILE calorimeter has clearly detected emission in the 600 keV - 2 MeV energy range.
