Pelassa (UAH) reports on behalf of the Fermi GBM Team:\n\n\"At 18:59:53.26 UT on 1 August 2014, the Fermi Gamma-Ray Burst Monitor\ntriggered and located GRB 140801A (trigger 428612396 / 140801792).\nAn optical transient was detected by the MASTER II robotic telescope\n(Lipunov et al. 2014, GCN 16653). The GBM on-ground location is\nconsistent with the OT location, which angle from the Fermi LAT\nboresight is 80 degrees.\n\nThe GBM light curve consists of two bright pulses followed by a\nshort tail, with a duration (T90) of about 7 s (50-300 keV).\n\nThe time-averaged spectrum from T0-2.048 s to T0+12.288 s is\nwell fit by a power law function with an exponential\nhigh-energy cutoff.  The power law index is -0.42 +/- 0.03 and\nthe cutoff energy, parameterized as Epeak, is 125 +/- 2 keV\n(Castor-statistics 697.99 for 610 d.o.f.).\nA Band function fits the spectrum equally well (Castor-statistics\n695.14 for 609 d.o.f.) with Epeak= 122 +/- 3 keV,\nalpha = -0.40 +/- 0.04 and beta = -3.6 +/- 0.4.\n\nThe event fluence (10-1000 keV) in this time interval is\n(1.22 +/- 0.01)E-05 erg/cm^2. The 1.024-sec peak photon flux measured\nstarting from T0+0.832 s in the 10-1000 keV band\nis 22.6 +/- 0.4 ph/s/cm^2.\n\nThe spectral analysis results presented above are preliminary;\nfinal results will be published in the GBM GRB Catalog.\"",
