Veres (UAH) and A. von Kienlin (MPE)\nreport on behalf of the Fermi GBM Team:\n\n\"At 09:26:08.66 UT on 05 March 2018, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 180305A (trigger 541934773 / 180305393) which\nwas also detected by the Fermi LAT (Axelsson et al., GCN 22457).\nThe GBM on-ground location is consistent with the LAT position.\n\nThe angle from the Fermi LAT boresight at the GBM trigger time is 70 degrees.\n\nThe GBM light curve consists of a single bright pulse\nwith a duration (T90) of about 12.5 s (50-300 keV).\nThe time-averaged spectrum from T0 to T0+24.1 s is best fit by\na Band function with Epeak= 334 +/- 10 keV, alpha = -0.48 +/- 0.02\nand beta = 2.29 +/- 0.07.\n\nThe event fluence (10-1000 keV) in this time interval is\n(3.302 +/- 0.023)E-5 erg/cm^2. The 1-sec peak photon flux measured\nstarting from T0+3.65 s in the 10-1000 keV band\nis 32.2 +/- 0.5 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
