//////////////////////////////////////////////////////////////////////// TITLE: GCN CIRCULAR NUMBER: 31540 SUBJECT: GRB 220201A: Fermi GBM Final Localization DATE: 22/02/01 18:32:13 GMT FROM: Rachel Hamburg at UAH The Fermi Gamma-Ray Burst Monitor (GBM) team reports the detection of a likely long GRB. At 16:11:15.73 UT on 01 February 2022, the triggered and located GRB 220201A (trigger 665424680 / 220201674). The on-ground calculated location, using the GBM trigger data, is RA = 14.7, DEC = -38.7 (J2000 degrees, equivalent to +00h 59m, -38d 41'), with a statistical uncertainty of 4.4 degrees. The angle from the Fermi LAT boresight is 16 degrees.
