- Аннотация: MASTER-Kislovodsk robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) started inspect of the Fermi GRB 220418A ( Fermi GBM team, GCN 31914) errorbox 7665 sec after notice time and 7697 sec after trigger time at 2022-04-18 18:00:16 UT, with upper limit up to 13.9 mag. The observations began at zenith distance = 75 deg. The sun altitude is -20.9 deg. The galactic latitude b = 4 deg., longitude l = 106 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1946689 We obtain a following upper limits.
