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 GRB200619.11 (trigger No 614226976,01h 56m 55.92s , +36d 43m 01.2s, R=5.32) errorbox 54 sec after notice time and 82 sec after trigger time at 2020-06-19 02:37:34 UT, with upper limit up to 16.5 mag. The observations began at zenith distance = 79 deg. The sun altitude is -33.9 deg. The galactic latitude b = -24 deg., longitude l = 138 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1385503 We obtain a following upper limits.
