//////////////////////////////////////////////////////////////////////// TITLE: GCN CIRCULAR NUMBER: 9097 SUBJECT: GRB 090403: Fermi GBM detection DATE: 09/04/06 15:22:07 GMT FROM: Sheila McBreen at MPE Sheila McBreen (UCD/MPE) reports on behalf of the Fermi GBM Team: "At 07:32:42.13 UT on 03 April 2009, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 090403 (trigger 260436764 / 090403314). The on-ground calculated location, using the GBM trigger data, is RA = 65.2, DEC = +47.1 (J2000 degrees, equivalent to 04 h 21 m, +47 d 06'), with an uncertainty of 8.5 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 42 degrees. The GBM light curve consists of one pulse with a duration of about 16 s. Since the source is weak, the time-averaged spectrum is poorly constrained."
