MASTER-Kislovodsk robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) started inspect of the Fermi GRB 211201A ( Fermi GBM team, GCN 31155) errorbox 1138 sec after notice time and 1166 sec after trigger time at 2021-12-01 21:02:19 UT, with upper limit up to 12.7 mag. The observations began at zenith distance = 75 deg. The sun altitude is -68.9 deg.
The galactic latitude b = -56 deg., longitude l = 92 deg.
Real time updated cover map and OT discovered available here:
