The Fermi GBM team reports the detection of a likely LONG GRB
At 03:56:02 UT on 6 Jun 2021, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 210606A (trigger 644644567.122922 / 210606164).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 177.6, Dec = -0.5 (J2000 degrees, equivalent to J2000 11h 50m, 0d 30'), with a statistical uncertainty of 11.4 degrees.
The angle from the Fermi LAT boresight is 110.0 degrees.
