MASTER-Kislovodsk robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) was pointed to the Swift GRB200109.07 (trigger No 948361,20h 28m 41.04s , +53d 00m 10.8s, R=0.05) errorbox  12 sec after notice time and 70 sec after trigger time at 2020-01-09 01:47:26 UT, with upper limit up to  17.9 mag. The observations began at zenith distance = 75 deg. The sun  altitude  is -31.2 deg. 

The galactic latitude b =  8 deg., longitude l = 90 deg.
