Fermi trigger No 721006392: Global MASTER-Net observations report

MASTER-Tavrida robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Lomonosov MSU, SAI Crimea astronomical station) started inspect of the Fermi GRB231106.98 (trigger No 721006392,08h 17m 40.80s , +53d 17m 24.0s, R=8.02) errorbox 12562 sec after notice time and 80126 sec after trigger time at 2023-11-07 21:48:34 UT, with upper limit up to 19.1 mag. The observations began at zenith distance = 47 deg. The sun altitude is -61.9 deg. The galactic latitude b = 35 deg., longitude l = 165 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2297251 We obtain a following upper limits.
