The Fermi GBM team reports the detection of a likely LONG GRB
At 17:36:11 UT on 11 Feb 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230211A (trigger 697829776.865304 / 230211733).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 59.2, Dec = 51.7 (J2000 degrees, equivalent to J2000 03h 56m, 51d 42'), with a statistical uncertainty of 14.6 degrees.
The angle from the Fermi LAT boresight is 77.0 degrees.
