TITLE: GCN CIRCULAR
NUMBER: 28232
SUBJECT: GRB 200809A: Fermi GBM Final Real-time Localization
DATE: 20/08/09 05:14:46 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 05:04:31 UT on 9 Aug 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 200809A (trigger 618642276.564984 / 200809211).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 205.1, Dec = -26.4 (J2000 degrees, equivalent to J2000 13h 40m, -26d 23'), with a statistical uncertainty of 5.2 degrees.
The angle from the Fermi LAT boresight is 17.0 degrees.
