GCN Circular 45115

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

"At 10:11:16.89 UT on 08 July 2026, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 260708A (trigger 805198281/260708424).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 227.4, Dec = -44.5 (J2000 degrees, equivalent to J2000 15h 09m, -44d 30'), with a statistical uncertainty of 1.6 degrees.

The angle from the Fermi LAT boresight is 43 degrees.
