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) started inspect of the Fermi GRB220915.02 (trigger No 684894705,09h 02m 43.20s , +04d 16m 48.0s, R=3.43) errorbox  68497 sec after notice time and 1 days 29299 sec after trigger time at 2022-09-16 08:39:59 UT, with upper limit up to  16.5 mag. The observations began at zenith distance = 79 deg. The sun  altitude  is -24.8 deg. 

The galactic latitude b = 31 deg., longitude l = 226 deg.
