Yu (MPE) report on behalf of the Fermi GBM Team:\n\n\"At 04:09:10.06 UT on 03 Feb 2015, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 150203A (trigger 444629353 / 150203173), which\nwas also detected by Swift (Ukwatta et al. 2015, GCN 17377). The GBM\non-ground location is consistent with the Swift position. The angle from\nthe Fermi LAT boresight is 97 degrees.\n\nThe GBM light curve shows a single pulse with a duration (T90) of\nabout 26 s (50-300 keV). The time-averaged spectrum from T0-2.048 s\nto T0+ 27.648 s is well fit by a power law function with an exponential\nhigh-energy cutoff. The power law index is -0.82 +/- 0.32 and the cutoff\nenergy, parameterized as Epeak, is 59 +/- 8 keV.\n\nThe event fluence (10-1000 keV) in this time interval is\n(1.29 +/- 0.13)E-06 erg/cm^2. The 1.024-sec peak photon flux measured\nstarting from T0+13.952 s in the 10-1000 keV band is 1.8 +/- 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.\"",
