The Fermi GBM team reports the detection of a likely SHORT GRB
At 22:17:19 UT on 13 May 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230513A (trigger 705709044.428824 / 230513929).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 160.7, Dec = 27.9 (J2000 degrees, equivalent to J2000 10h 42m, 27d 53'), with a statistical uncertainty of 7.5 degrees.
The angle from the Fermi LAT boresight is 89.0 degrees.
