Gabovich (Blagoveschensk Educational State University) MASTER-SAAO robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in South Africa (South African Astronomical Observatory) was pointed to the Swift GRB231214.85 (trigger No 1202386,20h 22m 56.64s , -72d 26m 09.6s, R=0.05) errorbox 81 sec after notice time and 103 sec after trigger time at 2023-12-14 20:26:11 UT, with upper limit up to 18.5 mag. The observations began at zenith distance = 65 deg. The sun altitude is -27.0 deg. The galactic latitude b = -33 deg., longitude l = 322 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2332686 We obtain a following upper limits.
