The observations began at zenith distance = 64 deg. The sun altitude is -25.2 deg. MASTER-Kislovodsk robotic telescope located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) started inspect of the Fermi GRB251113.38 errorbox 1 days 30851 sec after notice time and 1 days 30882 sec after trigger time at 2025-11-14 17:43:53 UT, with upper limit up to 16.8 mag. The observations began at zenith distance = 75 deg. The sun altitude is -42.9 deg. The galactic latitude b = 7 deg., longitude l = 49 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=3041181 We obtain a following upper limits.
