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 GRB191213.78 (trigger No 597955752,22h 04m 14.40s , -13d 56m 24.0s, R=6.67) errorbox 484 sec after notice time and 724 sec after trigger time at 2019-12-13 19:01:12 UT, with upper limit up to 19.2 mag. Observations started at twilight. The observations began at zenith distance = 49 deg. The sun altitude is -11.5 deg. MASTER-SAAO robotic telescope located in South Africa (South African Astronomical Observatory) started inspect of the Fermi GRB191213.78 errorbox 503 sec after notice time and 743 sec after trigger time at 2019-12-13 19:01:31 UT, with upper limit up to 18.8 mag. Observations started at twilight. The observations began at zenith distance = 60 deg. The sun altitude is -15.2 deg. The galactic latitude b = -49 deg., longitude l = 44 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=1225197 We obtain a following upper limits.
