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

"At 10:45:40 UT on 22 March 2026, the Fermi Gamma-ray Burst Monitor (GBM)
triggered and located GRB 260322A (trigger 795869144/260322448).

The on-ground calculated location, using the Fermi GBM trigger data,
is RA = 301.0, Dec = -61.8 (J2000 degrees, equivalent to J2000 20h 3m, -61d 46'),
with a statistical uncertainty of 7.9 degrees.

The angle from the Fermi LAT boresight is 59.0 degrees.
