2026-07-08T14:17:47.587Z | rev 0 | event: GRB 260708A
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.
