TITLE: GCN CIRCULAR
NUMBER: 40668
SUBJECT: GRB 250610A: Fermi GBM Final Real-time Localization
DATE: 25/06/10 13:58:44 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 13:48:25 UT on 10 Jun 2025, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 250610A (trigger 771256110.581806 / 250610575).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 359.9, Dec = 65.1 (J2000 degrees, equivalent to J2000 23h 59m, 65d 05'), with a statistical uncertainty of 1.0 degrees.
The angle from the Fermi LAT boresight is 0.0 degrees.
