GCN Circular 22896
S.Poolakkil and C. Meegan (both UAH) report on behalf of the Fermi GBM Team: "At 21:01:40.50 UT on 03 July 2018, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 180703A (trigger 552344505 / 180703876), which was also detected by the Fermi LAT (Racusin et al. 2018, GCN 22883). The GBM on-ground location is consistent with the LAT position. The angle from the Fermi LAT boresight at the GBM trigger time is 44 degrees. The GBM light curve shows a single peak with a duration (T90) of about 20.2 s (50-300 keV). The time-averaged spectrum from T0-3.1 s to T0+25.6 s is best fit by a Band function with Epeak = 360 +/- 33 keV, alpha = -0.80 +/- 0.04 and beta = -1.95 +/- 0.08. The event fluence (10-1000 keV) in this time interval is (2.001 +/- 0.043)E-05 erg/cm^2. The 1-sec peak photon flux measured starting from T0+3.52 s in the 10-1000 keV band is 11.1 +/- 0.25 ph/s/cm^2. The spectral analysis results presented above are preliminary; final results will be published in the GBM GRB Catalog."
