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 GRB220926.34 (trigger No 1125350,16h 19m 42.00s , -15d 50m 13.6s, R=0.05) errorbox 33953 sec after notice time and 34030 sec after trigger time at 2022-09-26 17:37:44 UT, with upper limit up to 18.3 mag. Observations started at twilight. The observations began at zenith distance = 44 deg. The sun altitude is -13.6 deg. The galactic latitude b = 23 deg., longitude l = 359 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2101427 We obtain a following upper limits.
