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 GRB220829.61 (trigger No 683476673,03h 07m 12.00s , +55d 21m 00.0s, R=1) errorbox 42739 sec after notice time and 81444 sec after trigger time at 2022-08-30 13:15:13 UT, with upper limit up to 18.2 mag. The observations began at zenith distance = 56 deg. The sun altitude is -24.0 deg.
The galactic latitude b = -2 deg., longitude l = 142 deg.
Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2071460
We obtain a following upper limits.
