MASTER-Amur robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Blagoveshchensk State Pedagogical University) started inspect of the Fermi GRB220825.86 (trigger No 683152759,08h 46m 12.00s , +29d 52m 01.2s, R=32.47) errorbox  72583 sec after notice time and 72614 sec after trigger time at 2022-08-26 16:49:29 UT, with upper limit up to  18.9 mag. The observations began at zenith distance = 63 deg. The sun  altitude  is -27.3 deg. 

The galactic latitude b = 37 deg., longitude l = 195 deg.


Real time updated cover map and OT discovered available here:
