TITLE: GCN CIRCULAR NUMBER: 36222 SUBJECT: GRB 240422A: Fermi GBM Final Real-time Localization DATE: 24/04/22 02:51:32 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 LONG GRB
At 02:40:59 UT on 22 Apr 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240422A (trigger 735446464.467214 / 240422112).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 255.6, Dec = -67.4 (J2000 degrees, equivalent to J2000 17h 02m, -67d 24'), with a statistical uncertainty of 9.9 degrees.
The angle from the Fermi LAT boresight is 23.0 degrees.
