Sergienko (Blagoveschensk Educational State University) MASTER-Kislovodsk robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) started inspect of the Fermi GRB200103.68 (trigger No 599761015,23h 14m 52.08s , -48d 01m 01.2s, R=29.2) errorbox 225 sec after notice time and 257 sec after trigger time at 2020-01-03 16:21:07 UT, with upper limit up to 17.9 mag. The observations began at zenith distance = 77 deg. The sun altitude is -27.1 deg. MASTER-SAAO robotic telescope located in South Africa (South African Astronomical Observatory) started inspect of the Fermi GRB200103.68 errorbox 225 sec after notice time and 8820 sec after trigger time at 2020-01-03 18:43:50 UT, with upper limit up to 19.1 mag. Observations started at twilight. The observations began at zenith distance = 29 deg. The sun altitude is -10.8 deg. The galactic latitude b = -62 deg., longitude l = 338 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1248534 We obtain a following upper limits.
