GCN Circular 41395

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

"At 11:49:10.84 UT on 15 August 2025, the Fermi Gamma-ray Burst Monitor (GBM)
triggered and located GRB 250815A (trigger 776951355/250815492). The duration
and the spectrum suggest an SGR flare, but it is not near the galactic
plane, so further follow-up is encouraged.

The on-ground calculated location, using the Fermi GBM trigger data,
is RA = 221.57, Dec = -1.10 (J2000 degrees, equivalent to J2000 14h 46m, -1d 6'),
with a statistical uncertainty of 7.79 degrees.

The angle from the Fermi LAT boresight is 30 degrees.
