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 GRB221012.87 (trigger No 10069,19h 35m 07.39s , +21d 54m 05.8s, R=0.0463333) errorbox  8892 sec after notice time and 8901 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.
