TITLE: GCN CIRCULAR
NUMBER: 40784
SUBJECT: GRB 250619A: Fermi GBM Final Real-time Localization
DATE: 25/06/19 15:25:10 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 15:14:36 UT on 19 Jun 2025, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 250619A (trigger 772038881.892868 / 250619635).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 35.1, Dec = 27.0 (J2000 degrees, equivalent to J2000 02h 20m, 27d 00'), with a statistical uncertainty of 3.9 degrees.
The angle from the Fermi LAT boresight is 40.0 degrees.
