The Fermi GBM team reports the detection of a likely LONG GRB

At 21:06:43 UT on 2 Jul 2025, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 250702F (trigger 773183208.102296 / 250702880).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 215.8, Dec = 16.6 (J2000 degrees, equivalent to J2000 14h 23m, 16d 36'), with a statistical uncertainty of 2.2 degrees.

The angle from the Fermi LAT boresight is 43.0 degrees.
