- 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 220721A ( Fermi GBM team, GCN 32420) errorbox 360 sec after notice time and 409 sec after trigger time at 2022-07-21 00:37:15 UT, with upper limit up to 19.6 mag. The observations began at zenith distance = 29 deg. The sun altitude is -62.5 deg. The galactic latitude b = -72 deg., longitude l = 346 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2036832 We obtain a following upper limits.
