- 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 220417A ( Fermi GBM team, GCN 31912) errorbox 10933 sec after notice time and 10962 sec after trigger time at 2022-04-17 16:55:18 UT, with upper limit up to 18.2 mag. Observations started at twilight. The observations began at zenith distance = 43 deg. The sun altitude is -9.1 deg. The galactic latitude b = 10 deg., longitude l = 205 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1945725 We obtain a following upper limits.
