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

"At 08:23:49.89 UT on 13 February 2026, the Fermi Gamma-ray Burst Monitor (GBM)
triggered and located GRB 260213A (trigger 792663834/260213350).

The on-ground calculated location, using the Fermi GBM trigger data,
is RA = 244.99, Dec = -18.22 (J2000 degrees, equivalent to J2000 16h 19m, -18d 13'),
with a statistical uncertainty of 11.02 degrees.

The angle from the Fermi LAT boresight is 67 degrees.
