TITLE: GCN CIRCULAR NUMBER: 9132 SUBJECT: GRB 090412: Fermi GBM detection DATE: 09/04/16 17:49:35 GMT FROM: Rob Preece at UAH Rob Preece (UAH) reports on behalf of the Fermi GBM Team: "At 01:28:05.25 UT on 12 April 2009, the Fermi Gamma-Ray Burst Monitor triggered and located a weak GRB 090412 (trigger 261192487 / 090412061). The on-ground calculated location, using the GBM trigger data, is RA = 0.3, DEC = -49.8 (J2000 degrees, equivalent to 00 h 01 m, -48 d 48 '), with an uncertainty of 9.6 degrees (radius, 1-sigma containment, statistical only; there is additionally a systematic error which is currently estimated to be 2 to 3 degrees). The angle from the Fermi LAT boresight is 71 degrees. The GBM light curve consists of a weak pulse with a duration (T90) of about 0.5 s (8-1000 keV). Since the source is very weak, it is not possible to perform any spectral analysis."
