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 220211B ( Fermi GBM team, GCN 31578) errorbox 288 sec after notice time and 320 sec after trigger time at 2022-02-11 15:51:48 UT, with upper limit up to 16.9 mag. Observations started at twilight. The observations began at zenith distance = 43 deg. The sun altitude is -14.3 deg.
The galactic latitude b = -16 deg., longitude l = 117 deg.
Real time updated cover map and OT discovered available here:
