TITLE: GCN CIRCULAR
NUMBER: 25642
SUBJECT: GRB 190904A: Fermi GBM Final Real-time Localization
DATE: 19/09/04 04:21:19 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 04:11:00 UT on 4 Sep 2019, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 190904A (trigger 589263065.737252 / 190904174).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 35.9, Dec = -25.0 (J2000 degrees, equivalent to J2000 02h 23m, -25d 00'), with a statistical uncertainty of 12.7 degrees.
The angle from the Fermi LAT boresight is 98.0 degrees.
