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

At 04:29:02 UT on 11 Apr 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 200411A (trigger 608272147.522124 / 200411187).

The on-ground calculated location, using the Fermi GBM trigger data, is RA = 69.6, Dec = -60.3 (J2000 degrees, equivalent to J2000 04h 38m, -60d 17'), with a statistical uncertainty of 24.1 degrees.

The angle from the Fermi LAT boresight is 128.0 degrees.
