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 GRB221013.33 (trigger No 687340841,19h 36m 43.92s , +21d 30m 00.0s, R=7.98) errorbox  5384 sec after notice time and 5393 sec after trigger time at 2022-10-13 09:30:29 UT, with upper limit up to  16.9 mag. Observations started at twilight.  The observations began at zenith distance = 24 deg. The sun  altitude  is -8.1 deg. 

The galactic latitude b = -0 deg., longitude l = 57 deg.
