The Fermi GBM team reports the detection of a likely SHORT GRB
At 15:28:23 UT on 8 Nov 2020, the Fermi Gamma-ray Burst Monitor (GBM) triggered and located GRB 201108A (trigger 626542108.26729 / 201108645).
The on-ground calculated location, using the Fermi GBM trigger data, is RA = 289.0, Dec = 35.9 (J2000 degrees, equivalent to J2000 19h 15m, 35d 53'), with a statistical uncertainty of 9.7 degrees.
The angle from the Fermi LAT boresight is 66.0 degrees.

MASTER-Tavrida robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Lomonosov MSU, SAI Crimea astronomical station) started inspect of the Fermi GRB 201108A ( Fermi GBM team, GCN 28866) errorbox 359 sec after notice time and 389 sec after trigger time at 2020-11-08 15:34:52 UT, with upper limit up to 16.7 mag. Observations started at twilight. The observations began at zenith distance = 17 deg. The sun altitude is -13.0 deg.
The galactic latitude b = 11 deg., longitude l = 68 deg.
Real time updated cover map and OT discovered available here:
