TITLE: GCN CIRCULAR
NUMBER: 36699
SUBJECT: GRB 240619B: Fermi GBM Final Real-time Localization
DATE: 24/06/19 11:21:29 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 11:10:47 UT on 19 Jun 2024, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 240619B (trigger 740488252.364386 / 240619466).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 116.0, Dec = 18.4 (J2000 degrees, equivalent to J2000 07h 44m, 18d 23'), with a statistical uncertainty of 20.9 degrees.
The angle from the Fermi LAT boresight is 68.0 degrees.
