TITLE: GCN CIRCULAR
NUMBER: 27350
SUBJECT: GRB 200308A: Fermi GBM Final Real-time Localization
DATE: 20/03/08 22:45:34 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely SHORT GRB
At 22:35:15 UT on 8 Mar 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 200308A (trigger 605399720.791064 / 200308941).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 327.4, Dec = -27.8 (J2000 degrees, equivalent to J2000 21h 49m, -27d 48'), with a statistical uncertainty of 11.9 degrees.
The angle from the Fermi LAT boresight is 64.0 degrees.
