MASTER-OAFA robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Argentina (OAFA observatory of San Juan National University) was pointed to the Swift GRB 220813A ( M. G. Bernardini et al., GCN 32465) errorbox 40368 sec after notice time and 40414 sec after trigger time at 2022-08-14 06:36:37 UT, with upper limit up to 17.0 mag. The observations began at zenith distance = 72 deg. The sun altitude is -58.5 deg.
The galactic latitude b = -31 deg., longitude l = 237 deg.
Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2055501
We obtain a following upper limits.
