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

At 02:16:36 UT on 1 Jul 2026, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 260701A (trigger 804565001.437744 / 260701095).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 294.2, Dec = -51.3 (J2000 degrees, equivalent to J2000 19h 36m, -51d 17'), with a statistical uncertainty of 6.7 degrees.

The angle from the Fermi LAT boresight is 68.0 degrees.
