MASTER-IAC robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Spain (IAC Teide Observatory) was pointed to the Swift GRB200207.13 (trigger No 954840,10h 54m 29.52s , -49d 34m 51.6s, R=0.05) errorbox  70 sec after notice time and 878 sec after trigger time at 2020-02-07 03:16:56 UT, with upper limit up to  16.9 mag. The observations began at zenith distance = 78 deg. The sun  altitude  is -59.6 deg. 

The galactic latitude b =  9 deg., longitude l = 285 deg.
