The Fermi GBM team reports the detection of a likely LONG GRB
At 16:03:05 UT on 5 Jan 2021, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 210105A (trigger 631555390.920328 / 210105669).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 71.0, Dec = -36.8 (J2000 degrees, equivalent to J2000 04h 44m, -36d 47'), with a statistical uncertainty of 9.6 degrees.
The angle from the Fermi LAT boresight is 65.0 degrees.
