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 GRB231214.85 (trigger No 724278269,20h 08m 55.20s , -72d 07m 12.0s, R=1.01) errorbox  69 sec after notice time and 106 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 = -32 deg., longitude l = 323 deg.


Real time updated cover map and OT discovered available here:
