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 GRB231206.79 (trigger No 723581802,02h 47m 28.80s , +03d 54m 36.0s, R=8.34) errorbox 569 sec after notice time and 604 sec after trigger time at 2023-12-06 19:06:41 UT, with upper limit up to 19.9 mag. The observations began at zenith distance = 46 deg. The sun altitude is -17.1 deg.
MASTER-Tavrida robotic telescope located in Russia (Lomonosov MSU, SAI Crimea astronomical station) started inspect of the Fermi GRB231206.79 errorbox 1092 sec after notice time and 1127 sec after trigger time at 2023-12-06 19:15:24 UT, with upper limit up to 19.4 mag. The observations began at zenith distance = 40 deg. The sun altitude is -54.4 deg.
The galactic latitude b = -48 deg., longitude l = 170 deg.
