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 Integral GRB221012.91 (trigger No 10071,19h 35m 04.02s , +21d 52m 28.7s, R=0.0463333) errorbox 6160 sec after notice time and 6170 sec after trigger time at 2022-10-12 23:27:10 UT, with upper limit up to 17.2 mag. Observations started at twilight. The observations began at zenith distance = 54 deg. The sun altitude is -10.0 deg.
The galactic latitude b = 0 deg., longitude l = 58 deg.
