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

At 21:21:00 UT on 27 Jun 2022, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 220627A (trigger 678057665.085772 / 220627890).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 211.5, Dec = -35.1 (J2000 degrees, equivalent to J2000 14h 05m, -35d 06'), with a statistical uncertainty of 4.2 degrees.

The angle from the Fermi LAT boresight is 20.0 degrees.
