(UAH) report on behalf of the Fermi GBM Team:\n\n\"At 20:33:15.25  UT, on 2015 May 13, the Fermi\nGamma-Ray Burst Monitor triggered and located GRB 150513A\n(trigger 453241998 / 150513856) which was also detected\nby Swift (Kocevski  et al. 2015, GCN 17810) and Fermi/LAT\n(Kocevski et al. 2015, GCN 17812). The GBM on-ground location\nis consistent with the Swift position. The angle from the\nFermi LAT boresight is about 45 degrees.\n\nThe GBM light curve shows two peaks separated by about 150 s\nwith a duration (T90) of 165 s (50-300 keV). The time-averaged\nspectrum from T0-161.5 s to T0+4.3 s is well fit by a BAND function\nwith Epeak = 252 +/- 63 keV, alpha = -0.9 +/- 0.1, and\nbeta = -1.69 +/- 0.06.\n\nThe event fluence (10-1000 keV) in this time interval is\n(1.36 +/- 0.04)E-05 erg/cm^2. The 1 second peak photon\nflux measured starting from T0+0.2 s in the 10-1000 keV\nband is 4.1 +/- 0.3 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
