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

"At 05:42:33.65 UT on 07 February 2026, the Fermi Gamma-ray Burst Monitor (GBM)
triggered and located GRB 260207A (trigger 792135758/260207238).

The on-ground calculated location, using the Fermi GBM trigger data,
is RA = 160.45, Dec = -34.44 (J2000 degrees, equivalent to J2000 10h 41m, -34d 26'),
with a statistical uncertainty of 3.29 degrees.

The angle from the Fermi LAT boresight is 37 degrees.
