TITLE: GCN CIRCULAR
NUMBER: 33542
SUBJECT: GRB 230330A: Fermi GBM Final Real-time Localization
DATE: 23/03/30 04:44:38 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 04:34:29 UT on 30 Mar 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230330A (trigger 701843674.478352 / 230330191).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 282.7, Dec = -12.6 (J2000 degrees, equivalent to J2000 18h 50m, -12d 35'), with a statistical uncertainty of 4.0 degrees.
The angle from the Fermi LAT boresight is 47.0 degrees.
