The Fermi GBM team reports the detection of a likely LONG GRB
At 02:42:40 UT on 3 Sep 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 200903B (trigger 620793765.87189 / 200903113).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 53.9, Dec = -13.0 (J2000 degrees, equivalent to J2000 03h 35m, -13d 00'), with a statistical uncertainty of 4.8 degrees.
The angle from the Fermi LAT boresight is 32.0 degrees.

report on behalf of the Insight-HXMT team:
At 2020-09-03T02:42:40.87 (T0), Insight-HXMT/HE detected
GRB 200903B (trigger ID: HEB200903112) in a routine search of the data,
which also triggered Fermi-GBM (Fermi GBM team, GCN#28352).
The Insight-HXMT/HE light curve mainly consists of multiple
pulses with a duration (T90) of 70.88 s measured from T0-27.86 s.
The 1-ms peak rate, measured from T0+38.32 s, is 622 cnts/sec.
The total counts from this burst is 11739 counts.
URL_LC: http://twiki.ihep.ac.cn/pub/HXMT/GRBList/HEB200903112_lc.jpg
All measurements above are made with the CsI detectors operating in the
regular mode with the energy range of about 80-800 keV (deposited energy).
Only gamma-rays with energy greater than about 200 keV can penetrate
the spacecraft and leave signals in the CsI detectors installed inside
of the telescope.
Insight-HXMT is the first Chinese space X-ray telescope, which was
funded jointly by the China National Space Administration (CNSA) and
the Chinese Academy of Sciences (CAS).
