- 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 220408B ( Fermi GBM team, GCN 31854) errorbox 38858 sec after notice time and 38887 sec after trigger time at 2022-04-08 18:16:12 UT, with upper limit up to 17.9 mag. The observations began at zenith distance = 33 deg. The sun altitude is -24.1 deg. The galactic latitude b = -25 deg., longitude l = 259 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1936782 We obtain a following upper limits.
