TITLE: GCN CIRCULAR
NUMBER: 29115
SUBJECT: GRB 201222A: Fermi GBM Final Real-time Localization
DATE: 20/12/22 00:22:39 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely SHORT GRB
At 00:12:18 UT on 22 Dec 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 201222A (trigger 630288743.68768 / 201222009).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 215.7, Dec = 13.5 (J2000 degrees, equivalent to J2000 14h 22m, 13d 30'), with a statistical uncertainty of 8.1 degrees.
The angle from the Fermi LAT boresight is 6.0 degrees.
