Аннотация:MASTER-SAAO robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in South Africa (South African Astronomical Observatory) was pointed to the Swift GRB210222.94 (trigger No 1034325,10h 18m 29.04s , -14d 53m 52.8s, R=0.05) errorbox 235 sec after notice time and 276 sec after trigger time at 2021-02-22 22:42:03 UT, with upper limit up to 17.9 mag. The observations began at zenith distance = 17 deg. The sun altitude is -48.0 deg. The galactic latitude b = 34 deg., longitude l = 258 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1553237 We obtain a following upper limits.
