Sergienko (Blagoveschensk Educational State University) 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) started inspect of the Fermi GRB200303.11 (trigger No 604895668,13h 49m 45.60s , +50d 45m 00.0s, R=3.8) errorbox 174 sec after notice time and 182 sec after trigger time at 2020-03-03 02:37:26 UT, with upper limit up to 17.2 mag. The observations began at zenith distance = 31 deg. The sun altitude is -61.2 deg. The galactic latitude b = 64 deg., longitude l = 101 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1303204 We obtain a following upper limits.
