TITLE: GCN CIRCULAR
NUMBER: 33603
SUBJECT: GRB 230410A: Fermi GBM Final Real-time Localization
DATE: 23/04/10 11:36:21 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 11:26:00 UT on 10 Apr 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230410A (trigger 702818765.135562 / 230410476).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 352.3, Dec = 22.9 (J2000 degrees, equivalent to J2000 23h 29m, 22d 53'), with a statistical uncertainty of 2.1 degrees.
The angle from the Fermi LAT boresight is 72.0 degrees.
