TITLE: GCN CIRCULAR
NUMBER: 41135
SUBJECT: GRB 250722A: Fermi GBM Final Real-time Localization
DATE: 25/07/22 11:19:47 GMT
FROM: Fermi GBM Team at MSFC/Fermi-GBM
The Fermi GBM team reports the detection of a likely LONG GRB
At 11:09:07 UT on 22 Jul 2025, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 250722A (trigger 774875352.002704 / 250722465).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 313.5, Dec = -63.3 (J2000 degrees, equivalent to J2000 20h 53m, -63d 17'), with a statistical uncertainty of 12.6 degrees.
The angle from the Fermi LAT boresight is 2.0 degrees.
