TITLE: GCN CIRCULAR
NUMBER: 33385
SUBJECT: GRB 230301A: Fermi GBM Final Real-time Localization
DATE: 23/03/01 06:50:48 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 06:40:10 UT on 1 Mar 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230301A (trigger 699345615.891978 / 230301278).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 319.1, Dec = 68.3 (J2000 degrees, equivalent to J2000 21h 16m, 68d 17'), with a statistical uncertainty of 3.0 degrees.
The angle from the Fermi LAT boresight is 15.0 degrees.
