Fermi trigger No 751554401: Global MASTER-Net observations report

MASTER-Tunka robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Applied Physics Institute, Irkutsk State University) started inspect of the Fermi GRB241025.55 (trigger No 751554401,16h 59m 28.80s , +08d 05m 24.0s, R=7.42) errorbox 83 sec after notice time and 125 sec after trigger time at 2024-10-25 13:08:42 UT, with upper limit up to 16.6 mag. The observations began at zenith distance = 78 deg. The sun altitude is -30.9 deg. The galactic latitude b = 28 deg., longitude l = 28 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2649020 We obtain a following upper limits.
