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

"At 07:23:59.29 UT on 02 May 2025, the Fermi Gamma-ray Burst Monitor (GBM)
triggered and located GRB 250502C (trigger 767863444/250502308).

The on-ground calculated location, using the Fermi GBM trigger data,
is RA = 239.16, Dec = -47.34 (J2000 degrees, equivalent to J2000 15h 56m, -47d 20'),
with a statistical uncertainty of 11.99 degrees.

The angle from the Fermi LAT boresight is 69 degrees.
