MASTER-Tunka robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Applied Physics Institute, Irkutsk State University) started inspect of the Fermi GRB200212.45 (trigger No 603197394,08h 27m 43.20s , +08d 48m 36.0s, R=17.85) errorbox 1916 sec after notice time and 1944 sec after trigger time at 2020-02-12 11:22:14 UT, with upper limit up to 13.7 mag. Observations started at twilight. The observations began at zenith distance = 54 deg. The sun altitude is -10.9 deg.
The galactic latitude b = 26 deg., longitude l = 216 deg.
