The Fermi GBM team reports the detection of a likely LONG GRB

At 01:32:06 UT on 20 Jun 2022, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 220620A (trigger 677381531.21551 / 220620064).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 109.4, Dec = 66.9 (J2000 degrees, equivalent to J2000 07h 17m, 66d 54'), with a statistical uncertainty of 2.6 degrees.

The angle from the Fermi LAT boresight is 133.0 degrees.
