TITLE: GCN CIRCULAR
NUMBER: 27699
SUBJECT: GRB 200507A: Fermi GBM Final Real-time Localization
DATE: 20/05/07 16:03:20 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 15:52:58 UT on 7 May 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 200507A (trigger 610559583.838602 / 200507662).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 57.8, Dec = 65.5 (J2000 degrees, equivalent to J2000 03h 51m, 65d 30'), with a statistical uncertainty of 2.2 degrees.
The angle from the Fermi LAT boresight is 46.0 degrees.
