- 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 GRB 220222B ( Fermi GBM team, GCN 31636) errorbox 437 sec after notice time and 466 sec after trigger time at 2022-02-22 19:31:53 UT, with upper limit up to 19.1 mag. The observations began at zenith distance = 70 deg. The sun altitude is -26.3 deg. The galactic latitude b = 29 deg., longitude l = 302 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1891717 We obtain a following upper limits.
