- 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 220905A ( Fermi GBM team, GCN 32518) errorbox 20955 sec after notice time and 20989 sec after trigger time at 2022-09-05 17:18:33 UT, with upper limit up to 18.8 mag. Observations started at twilight. The observations began at zenith distance = 64 deg. The sun altitude is -12.3 deg. The galactic latitude b = -65 deg., longitude l = 12 deg.Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2079144We obtain a following upper limits.
