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

"At 05:35:36.16 UT on 28 June 2023, the Fermi Gamma-ray Burst Monitor (GBM)
triggered and located GRB 230628A (trigger 709623341/230628233).

The on-ground calculated location, using the Fermi GBM trigger data,
is RA = 139.19, Dec = -11.54 (J2000 degrees, equivalent to J2000 9h 16m, -11d 32'),
with a statistical uncertainty of 16.84 degrees.

The angle from the Fermi LAT boresight is 51 degrees.
