The observations began at zenith distance = 63 deg. The sun altitude is -41.2 deg. MASTER-Kislovodsk robotic telescope located in Russia (Lomonosov MSU, Kislovodsk Solar Station of Pulkovo observatory) started inspect of the Fermi GRB 251006B errorbox 545 sec after notice time and 587 sec after trigger time at 2025-10-06 20:14:51 UT, with upper limit up to 14.9 mag. The observations began at zenith distance = 59 deg. The sun altitude is -51.1 deg. MASTER-Tunka robotic telescope located in Russia (Applied Physics Institute, Irkutsk State University) started inspect of the Fermi GRB 251006B errorbox 563 sec after notice time and 606 sec after trigger time at 2025-10-06 20:15:10 UT, with upper limit up to 16.7 mag. The observations began at zenith distance = 58 deg. The sun altitude is -28.3 deg. The galactic latitude b = -54 deg., longitude l = 177 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=3008721 We obtain a following upper limits.
