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 GRB231214.33 (trigger No 724233240,09h 11m 43.20s , -13d 25m 12.0s, R=6.25) errorbox  31345 sec after notice time and 44890 sec after trigger time at 2023-12-14 20:22:05 UT, with upper limit up to  14.5 mag. The observations began at zenith distance = 75 deg. The sun  altitude  is -68.3 deg. 

The galactic latitude b = 23 deg., longitude l = 244 deg.
