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) was pointed to the Integral GRB220311.69 (trigger No 75305,12h 16m 08.21s , +66d 45m 39.6s, R=0.0542) errorbox 45 sec after notice time and 53 sec after trigger time at 2022-03-11 16:34:45 UT, with upper limit up to 14.5 mag. The observations began at zenith distance = 16 deg. The sun altitude is -42.3 deg.
The galactic latitude b = 50 deg., longitude l = 128 deg.
Real time updated cover map and OT discovered available here:
