The Fermi GBM team reports the detection of a likely LONG GRB
At 12:04:06 UT on 10 May 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230510A (trigger 705413051.934178 / 230510503).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 322.3, Dec = 31.0 (J2000 degrees, equivalent to J2000 21h 29m, 31d 00'), with a statistical uncertainty of 2.6 degrees.
The angle from the Fermi LAT boresight is 14.0 degrees.
