The Fermi GBM team reports the detection of a likely LONG GRB
At 06:31:55 UT on 14 Apr 2026, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 260414A (trigger 797841120.53845 / 260414272).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 17.0, Dec = 39.8 (J2000 degrees, equivalent to J2000 01h 07m, 39d 47'), with a statistical uncertainty of 6.0 degrees.
The angle from the Fermi LAT boresight is 48.0 degrees.
