Circular_text TITLE: GCN CIRCULAR NUMBER: 9022 SUBJECT: GRB 090320C: Fermi GBM Detection DATE: 09/03/23 21:38:57 GMT FROM: Vandiver Chaplin at UAH/Fermi-GBM V.Chaplin (UAH) reports on behalf of the Fermi GBM Team: "At 01:05:10.53 UT on 20 March 2009, the Fermi Gamma-Ray Burst Monitor triggered and located GRB 090320C (trigger 259203912 / 090320045). The on-ground calculated location, using the GBM trigger data, is RA = 108.2, DEC = -43.3 (J2000 degrees, equivalent to 7h 13m, -43d 18'), with an uncertainty of 15.0 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 40 degrees. The GBM light curve has a duration (T90) of about 4 s (8-1000 keV), with a peak at about T0-2 seconds. Since the source is weak, the time-averaged spectrum is poorly constrained."
