TITLE: GCN CIRCULAR
NUMBER: 33504
SUBJECT: GRB 230322A: Fermi GBM Final Real-time Localization
DATE: 23/03/22 21:08:07 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 20:57:41 UT on 22 Mar 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230322A (trigger 701211466.278488 / 230322873).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 12.3, Dec = 30.7 (J2000 degrees, equivalent to J2000 00h 49m, 30d 41'), with a statistical uncertainty of 7.3 degrees.
The angle from the Fermi LAT boresight is 100.0 degrees.
