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 GRB220608.32 (trigger No 676366592,06h 11m 52.01s , +32d 25m 00.1s, R=19.4333) errorbox  1 days 26962 sec after notice time and 1 days 26997 sec after trigger time at 2022-06-09 15:06:25 UT, with upper limit up to  16.2 mag. Observations started at twilight.  The observations began at zenith distance = 78 deg. The sun  altitude  is -16.9 deg. 

The galactic latitude b =  7 deg., longitude l = 180 deg.
