TITLE: GCN CIRCULAR NUMBER: 13013 SUBJECT: GRB 120302A: Fermi GBM Observation DATE: 12/03/07 08:19:13 GMT FROM: Veronique Pelassa at UAH V. Pelassa (UAH) reports on behalf of the Fermi GBM Team: "At 01:55:34.00 UT on March 02 2012, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 120302A (trigger 352346136 / 120302080), which was also found in the ground analysis of the Swift/BAT data (Sakamoto et al. 2012, GCN 13000). The Swift position is within the 3 sigma statistical error contour of the GBM on-ground location. The GBM light curve shows a short peak starting at about T-1.5s, followed by a plateau of about 20s and a weaker emission tail. The duration (T90) is of about 70 s (50-300 keV), which is consistent with the light curve observed by Swift considering the Swift/BAT data stops at T+30s (Sakamoto et al, GCN 13002). The time-averaged spectrum from T0-2 s to T0+67 s is well fit by a simple power law function with index -1.62 +/- 0.06 (Castor stat 453.64 for 367 d.o.f.), which is consistent with the results reported by Sakamoto et al (GCN 13002). The event fluence (10-1000 keV) in this time interval is (3.84 +/- 0.08)E-06 erg/cm^2. The 1.024-sec peak photon flux measured starting from T0-1.536 s in the 10-1000 keV band is 1.5 +/- 0.2 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."
