TITLE: GCN CIRCULAR
NUMBER: 33234
SUBJECT: GRB 230130A: Fermi GBM Final Real-time Localization
DATE: 23/01/30 05:04:09 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely SHORT GRB
At 04:53:48 UT on 30 Jan 2023, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 230130A (trigger 696747233.90504 / 230130204).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 204.2, Dec = 55.8 (J2000 degrees, equivalent to J2000 13h 36m, 55d 47'), with a statistical uncertainty of 6.3 degrees.
The angle from the Fermi LAT boresight is 20.0 degrees.
