TITLE: GCN CIRCULAR
NUMBER: 30758
SUBJECT: GRB 210903C: Fermi GBM Final Real-time Localization
DATE: 21/09/03 17:37:06 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 17:26:58 UT on 3 Sep 2021, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 210903C (trigger 652382823.653196 / 210903727).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 155.0, Dec = 22.0 (J2000 degrees, equivalent to J2000 10h 20m, 22d 00'), with a statistical uncertainty of 4.2 degrees.
The angle from the Fermi LAT boresight is 72.0 degrees.
