Аннотация: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 ofSan Juan National University) was pointed to the Swift GRB 220715B (E. Troja et al., GCN 32405) errorbox 3230 sec after notice time and 3257 sec after trigger time at 2022-07-15 23:18:59 UT, with upper limit up to 15.1 mag. The observations began at zenith distance = 34deg.
