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

At 22:25:25 UT on 6 Mar 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 200306B (trigger 605226330.32671 / 200306934).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 267.0, Dec = 24.5 (J2000 degrees, equivalent to J2000 17h 48m, 24d 30'), with a statistical uncertainty of 135.1 degrees.

The angle from the Fermi LAT boresight is 4.0 degrees.
