Sergienko (Blagoveschensk Educational State University) MASTER-Tunka robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Applied Physics Institute, Irkutsk State University) started inspect of the Fermi GRB 200614A ( Fermi GBM team, GCN 27940) errorbox 2103 sec after notice time and 2142 sec after trigger time at 2020-06-14 15:10:37 UT, with upper limit up to 17.1 mag. Observations started at twilight. The observations began at zenith distance = 58 deg. The sun altitude is -11.4 deg. The galactic latitude b = 30 deg., longitude l = 152 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1381664 We obtain a following upper limits.
