- 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 GRB220218.94 (trigger No 1093860,08h 55m 19.20s , +31d 59m 02.4s, R=0.05) errorbox 8 sec after notice time and 93 sec after trigger time at 2022-02-18 22:30:33 UT, with upper limit up to 16.8 mag. The observations began at zenith distance = 65 deg. The sun altitude is -46.2 deg. MASTER-Kislovodsk robotic telescope located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) was pointed to the Swift GRB220218.94 errorbox 32 sec after notice time and 117 sec after trigger time at 2022-02-18 22:30:56 UT, with upper limit up to 15.9 mag. The observations began at zenith distance = 29 deg. The sun altitude is -55.4 deg. The galactic latitude b = 40 deg., longitude l = 193 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1887825 We obtain a following upper limits.
