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) started inspect of the Fermi GRB211018.94 (trigger No 656288898,01h 02m 31.20s , -00d 40m 48.0s, R=1.23) errorbox 57 sec after notice time and 87 sec after trigger time at 2021-10-18 22:29:41 UT, with upper limit up to 16.4 mag. The observations began at zenith distance = 32 deg. The sun altitude is -48.1 deg. The galactic latitude b = -63 deg., longitude l = 130 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1756363 We obtain a following upper limits.
