The Fermi GBM team reports the detection of a likely LONG GRB
At 09:42:47 UT on 26 Jul 2022, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 220726A (trigger 680521372.015932 / 220726405).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 196.9, Dec = -61.8 (J2000 degrees, equivalent to J2000 13h 07m, -61d 47'), with a statistical uncertainty of 5.3 degrees.
The angle from the Fermi LAT boresight is 54.0 degrees.
