- 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 GRB220921.47 (trigger No 685452089,06h 17m 19.20s , -80d 35m 23.6s, R=11.45) errorbox 21513 sec after notice time and 21548 sec after trigger time at 2022-09-21 17:20:32 UT, with upper limit up to 18.8 mag. Observations started at twilight. The observations began at zenith distance = 67 deg. The sun altitude is -10.6 deg. The galactic latitude b = -28 deg., longitude l = 292 deg.Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2097261We obtain a following upper limits.
