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) started inspect of the Fermi GRB221012.65 (trigger No 687281393,20h 12m 12.00s , +10d 49m 48.0s, R=11.78) errorbox  783 sec after notice time and 836 sec after trigger time at 2022-10-12 15:43:44 UT, with upper limit up to  18.3 mag. Observations started at twilight.  The observations began at zenith distance = 46 deg. The sun  altitude  is -13.6 deg. 

MASTER-OAFA robotic telescope  located in Argentina (OAFA observatory of San Juan National University) started inspect of the Fermi GRB221012.65 errorbox  45530 sec after notice time and 45583 sec after trigger time at 2022-10-13 04:09:32 UT, with upper limit up to  16.7 mag. The observations began at zenith distance = 80 deg. The sun  altitude  is -51.3 deg. 

The galactic latitude b = -13 deg., longitude l = 53 deg.
