- 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) was pointed to the LAT GRB220921.46 (trigger No 685451164,04h 27m 09.60s , -40d 15m 00.0s, R=0.419833) errorbox 6084 sec after notice time and 31017 sec after trigger time at 2022-09-21 19:42:56 UT, with upper limit up to 16.0 mag. The observations began at zenith distance = 83 deg. The sun altitude is -39.3 deg. The galactic latitude b = -44 deg., longitude l = 244 deg.Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2097454We obtain a following upper limits.
