Cori Fletcher at USRA <>
The Fermi GBM team reports the detection of a likely SHORT GRB "At 10:46:08 UT on 25 May 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230525A (trigger 706704373/230525449). The on-ground calculated location, using the Fermi GBM trigger data, is RA = 45.27, Dec = 69.35 (J2000 degrees, equivalent to J2000 3h 1m, +69d 20'), with a statistical uncertainty of 6.75 degrees. The angle from the Fermi LAT boresight is 19 degrees. The skymap can be found here: The HEALPix FITS file, including the estimated localization systematic, can be found here: The GBM light curve can be found here:"
