2023-05-12T11:59:08Z (a year ago)
R. Hamburg at CNRS/IJCLab <>
The Fermi GBM team reports the detection of a Short Bright GRB.

At 06:27:45 UT on 12 May 2023, the Fermi Gamma-ray Burst Monitor (GBM)
triggered and located GRB 230512A (trigger 705565670/230512269).

The on-ground calculated location, using the Fermi GBM trigger data, is RA
= 277.62, Dec = +53.87 (J2000 degrees, equivalent to J2000 18h 30m, +53d
53'), with a statistical uncertainty of 1 degree.

The angle from the Fermi LAT boresight is 26 degrees.
