Salotti (ASI), on behalf of the AGILE \nTeam, report:\n\n\"The Swift localized GRB 080319C (Pagani et al., GCN 7442) triggered the \nMini-Calorimeter (MCAL) instrument onboard the AGILE satellite at 12:25:56 \nUT (=T0). The MCAL instrument covers the energy range 350 keV - 10 MeV, \nwithout imaging capabilities.\n\nThe MCAL light curve shows two main overlapping broad peaks, the first \npeaking at T0 and the second peaking at T0+9s in the 350-700 keV energy \nband. Above 700 keV only the first peak is still detected, with 5 sigma \ndetection also in the 1.4-2.8 MeV energy band. Using the preliminary \nin-flight calibration, we can estimate the 1-s peak flux in the 350-700 \nkeV energy band at T0 to be 2.0(-0.8,+0.9) photons/cm2/s.\n\nThe Swift localization is out of the field of view of the AGILE Gamma-Ray \nImaging Detector (GRID), sensitive in the 50 MeV - 50 GeV energy range. \nAnalysis of the GRID count rate does not show any detection. The event was \nwell outside of the SuperAGILE field of view as well, but the event passed \nthrough the collimator shield and was weakly detected in the count rate.\"\n\nWe incidentally note that the brighter GRB 080319B (Racusin et al. GCN \n7427) was not observed by the AGILE instruments due to Earth occultation.\n\nThis message may be cited.",
