The Fermi GBM team reports the detection of a likely LONG GRB
At 23:50:44 UT on 5 May 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 200505A (trigger 610415449.084498 / 200505994).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 81.1, Dec = -49.0 (J2000 degrees, equivalent to J2000 05h 24m, -49d 00'), with a statistical uncertainty of 3.5 degrees.
The angle from the Fermi LAT boresight is 17.0 degrees.

AGILE Team:
The AGILE satellite detected the long burst GRB 200505A, also reported
by Fermi/GBM (GCN #27689; trigger 610415449.084498/200505994) at
T0 = 2020-05-05 23:50:44 (UT).
The event is visible in the scientific ratemeters of the SuperAGILE (SA;
20-60 keV) detector. The event lasted ~15 s and released a total number of
~630 counts in the SA ratemeters (above a background of ~75 Hz). The SA
ratemeters light curve can be found at

.
Additional analysis of AGILE data is in progress.
