MASTER-Amur robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Blagoveshchensk State Pedagogical University) started inspect of the Fermi GRB220823.15 (trigger No 682918137,05h 31m 45.60s , +02d 26m 24.0s, R=3.01) errorbox 53666 sec after notice time and 53700 sec after trigger time at 2022-08-23 18:23:52 UT, with upper limit up to 18.1 mag. The observations began at zenith distance = 70 deg. The sun altitude is -18.2 deg.
The galactic latitude b = -16 deg., longitude l = 202 deg.
Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2065160
We obtain a following upper limits.
