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

At 16:15:24 UT on 29 May 2021, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 210529A (trigger 643997729.72023 / 210529677).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 15.8, Dec = -15.7 (J2000 degrees, equivalent to J2000 01h 03m, -15d 41'), with a statistical uncertainty of 10.9 degrees.

The angle from the Fermi LAT boresight is 69.0 degrees.
