Аннотация: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 211102A ( Fermi GBM team, GCN 31029) errorbox 26099 sec after notice time and 26125 sec after trigger time at 2021-11-02 15:21:29 UT, with upper limit up to 17.3 mag. Observations started at twilight. The observations began at zenith distance = 56 deg. The sun altitude is -9.4 deg. The galactic latitude b = -4 deg., longitude l = 133 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1772827 We obtain a following upper limits.
