TITLE: GCN CIRCULAR NUMBER: 35850 SUBJECT: GRB 240303B: Fermi GBM Final Localization DATE: 24/03/03 13:22:09 GMT FROM: rachel.hamburg@ijclab.in2p3.fr The Fermi GBM team reports the detection of a likely LONG GRB "At 12:18:51.24 UT on 03 March 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240303B (trigger 731161136 / 240303513). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 304.49, Dec = 1.26 (J2000 degrees, equivalent to J2000 20h 17m, +1d 15'), with a statistical uncertainty of 1.00 degrees. The angle from the Fermi LAT boresight is 96 degrees. The skymap can be found here: https://heasarc.gsfc.nasa.gov/FTP/fermi/data/gbm/triggers/2024/bn240303513/q...
