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 GRB200303.11 (trigger No 959431,14h 10m 47.52s , +51d 21m 36.0s, R=0.05) errorbox  124 sec after notice time and 148 sec after trigger time at 2020-03-03 02:37:26 UT, with upper limit up to  18.0 mag. The observations began at zenith distance = 31 deg. The sun  altitude  is -61.2 deg. 

The galactic latitude b = 62 deg., longitude l = 96 deg.
