TITLE: GCN CIRCULAR NUMBER: 33713 SUBJECT: GRB 230430A: Fermi GBM Final Real-time Localization DATE: 23/04/30 07:57:58 GMT FROM: Fermi GBM Team at MSFC/Fermi-GBM do_not_reply@GIOC.nsstc.nasa.gov
The Fermi GBM team reports the detection of a likely SHORT GRB
At 07:47:18 UT on 30 Apr 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230430A (trigger 704533643.80535 / 230430325).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 184.2, Dec = 40.8 (J2000 degrees, equivalent to J2000 12h 16m, 40d 47'), with a statistical uncertainty of 2.5 degrees.
The angle from the Fermi LAT boresight is 22.0 degrees.
