A. Goldstein et al., GCN 10358) triggered the Suzaku Wide-band All-sky Monitor (WAM) which covers an energy range of 50 keV - 5 MeV on 2010-01-31 17:30:58.052 UT (=T0). The observed light curve shows a multi-peaked structure lasting from T0-0.5s to T0+2s, followed by a weaker emission seen up to T0+4s with a duration (T90) of about 3.2 seconds. The fluence in 100 - 1000 keV was 2.72(-0...Full Text

"At 17:30:57.67 UT on 31 January 2010, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 100131A (trigger 286651859 / 100131730). The Fermi Observatory executed a maneuver following this trigger and tracked the burst location for the next 5 hours, subject to Earth-angle constraints. The on-ground calculated location, using the GBM trigger data, is RA = 120.4, DEC = +16.5 (J2000 degrees...Full Text
