MASTER-Kislovodsk robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) was pointed to the Integral GRB221012.61 (trigger No 10056,19h 34m 58.76s , +21d 53m 58.9s, R=0.047) errorbox  1832 sec after notice time and 1847 sec after trigger time at 2022-10-12 15:11:37 UT, with upper limit up to  15.4 mag. Observations started at twilight.  The observations began at zenith distance = 21 deg. The sun  altitude  is -7.7 deg. 

The galactic latitude b =  0 deg., longitude l = 58 deg.
