TITLE: GCN CIRCULAR
NUMBER: 34220
SUBJECT: GRB 230717A: Fermi GBM Final Real-time Localization
DATE: 23/07/17 02:59:46 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 02:49:08 UT on 17 Jul 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230717A (trigger 711254953.822542 / 230717117).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 106.8, Dec = 21.4 (J2000 degrees, equivalent to J2000 07h 07m, 21d 23'), with a statistical uncertainty of 11.3 degrees.
The angle from the Fermi LAT boresight is 64.0 degrees.
