The Fermi GBM team reports the detection of a likely SHORT GRB
Abstract
At 19:56:04 UT on 3 Dec 2023, the Fermi Gamma-ray Burst Monitor %(GBM) triggered and located GRB 231203B (trigger 723326169/231203831). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 197.3, Dec = +42.54 (J2000 degrees, equivalent to J2000 13h 09m, 42d 32'), with a statistical uncertainty of 15.9 degrees. The angle from the Fermi LAT boresight is 17.0 degrees.
