MASTER-SAAO robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in South Africa (South African Astronomical Observatory) was pointed to the LAT GRB220921.46 (trigger No 685451164,04h 27m 09.60s , -40d 15m 00.0s, R=0.419833) errorbox  6084 sec after notice time and 31017 sec after trigger time at 2022-09-21 19:42:56 UT, with upper limit up to  16.0 mag. The observations began at zenith distance = 83 deg. The sun  altitude  is -39.3 deg. 

The galactic latitude b = -44 deg., longitude l = 244 deg.
