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) started inspect of the Fermi GRB220826.22 (trigger No 683183601,21h 04m 02.40s , -14d 12m 00.0s, R=7.61) errorbox  16937 sec after notice time and 57286 sec after trigger time at 2022-08-26 21:08:03 UT, with upper limit up to  19.5 mag. The observations began at zenith distance = 18 deg. The sun  altitude  is -59.6 deg. 

The galactic latitude b = -36 deg., longitude l = 35 deg.


Real time updated cover map and OT discovered available here:
