Collazzi (NASA/ORAU) reports on behalf of the Fermi GBM \nTeam:\n\n\"At 17:25:17 UT on 03 July 2012, the Fermi Gamma-ray Burst Monitor\n(GBM) triggered and located GRB 120703A (trigger 363029120 / \n120703.726). This burst was also detected by Swift/BAT (Zhang, B.-B. \net al., GCN 13408).  The GBM on-ground position is consistent with \nthe Swift location.  The burst was also detected by Konus-Wind \n(Golenetskii, R. et al., GCN 13412).\n\nThe burst triggered an ARR (Automatic Repointing Request), causing \nFermi to slew so the LAT would point to the source.\n\nThe GBM light curve is similiar to the Swift detection. We observe a\nstrong central pulse with fainter wings, the total pulse having a \nwidth of ~20s. We measure the duration (T90) of about 9.216s \n(50-300 keV). The time-averaged spectrum from T0-2.048 to T0+14.336 s \nis best fit by a Comptonized power-law function, with Epeak = \n305.6 +/- 21.1 keV and alpha = -1.06 +/- 0.03.  The fluence \n(10-1000 keV) in this time interval is (9.154 +/- 0.246)E-06 erg/cm^2.\n\nThe burst is also fit well with a Band function with Epeak = \n238.5 +/- 26.5, keV alpha = -0.98 +/- 0.05, and beta = -2.08 +/- 0.12.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
