Аннотация: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) was pointed to the Swift GRB 211025A ( J.D. Gropp et al., GCN 30986) errorbox 63953 sec after notice time and 64035 sec after trigger time at 2021-10-25 22:57:35 UT, with upper limit up to 17.5 mag. The observations began at zenith distance = 76 deg. The sun altitude is -49.5 deg. The galactic latitude b = 64 deg., longitude l = 197 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1764428 We obtain a following upper limits.
