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 Swift GRB200216.56 (trigger No 956824,10h 41m 50.64s , +19d 27m 14.4s, R=0.05) errorbox  18 sec after notice time and 38 sec after trigger time at 2020-02-16 13:33:12 UT, with upper limit up to  17.6 mag. The observations began at zenith distance = 46 deg. The sun  altitude  is -43.8 deg. 

MASTER-Tunka robotic telescope  located in Russia (Applied Physics Institute, Irkutsk State University) was pointed to the Swift GRB200216.56 errorbox  49 sec after notice time and 69 sec after trigger time at 2020-02-16 13:33:43 UT, with upper limit up to  17.2 mag. The observations began at zenith distance = 61 deg. The sun  altitude  is -30.3 deg. 

The galactic latitude b = 60 deg., longitude l = 221 deg.
