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 GRB200529.04 (trigger No 974942,15h 55m 00.24s , -11d 03m 25.2s, R=0.05) errorbox  41 sec after notice time and 103 sec after trigger time at 2020-05-29 00:58:19 UT, with upper limit up to  17.8 mag. The observations began at zenith distance = 40 deg. The sun  altitude  is -40.4 deg. 

The galactic latitude b = 31 deg., longitude l = 359 deg.
