The Fermi GBM team reports the detection of a likely LONG GRB
At 11:09:58 UT on 30 May 2022, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 220530A (trigger 675601803.514142 / 220530465).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 159.4, Dec = 13.6 (J2000 degrees, equivalent to J2000 10h 37m, 13d 35'), with a statistical uncertainty of 8.5 degrees.
The angle from the Fermi LAT boresight is 86.0 degrees.
