Fermi trigger No 694232203: Global MASTER-Net observations report

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) started inspect of the Fermi GRB230101.09 (trigger No 694232203,13h 45m 12.00s , -21d 56m 24.0s, R=2.79) errorbox 33 sec after notice time and 72 sec after trigger time at 2023-01-01 02:17:51 UT, with upper limit up to 18.8 mag. Observations started at twilight. The observations began at zenith distance = 45 deg. The sun altitude is -14.5 deg. The galactic latitude b = 39 deg., longitude l = 320 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2188809 We obtain a following upper limits.
