Fermi trigger No 716419312: 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 GRB230914.89 (trigger No 716419312,11h 08m 36.00s , +20d 06m 00.0s, R=33.73) errorbox 10996 sec after notice time and 11008 sec after trigger time at 2023-09-15 00:25:16 UT, with upper limit up to 18.2 mag. The observations began at zenith distance = 70 deg. The sun altitude is -29.7 deg. The galactic latitude b = 66 deg., longitude l = 225 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2270502 We obtain a following upper limits.
