GCN 44779: GRB 260602B: Fermi GBM Final Localization

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

"At 22:41:31.26 UT on 02 June 2026, the Fermi Gamma-ray Burst Monitor (GBM)
triggered and located GRB 260602B (trigger 802132896/260602945).

The on-ground calculated location, using the Fermi GBM trigger data,
is RA = 187.55, Dec = -16.61 (J2000 degrees, equivalent to J2000 12h 30m, -16d 36'),
with a statistical uncertainty of 4.88 degrees.

The angle from the Fermi LAT boresight is 71 degrees.
