Fermi trigger No 751563375: 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 GRB241025.65 (trigger No 751563375,10h 02m 48.00s , +46d 26m 24.0s, R=3.33) errorbox 96 sec after notice time and 132 sec after trigger time at 2024-10-25 15:38:23 UT, with upper limit up to 14.4 mag. Observations started at twilight. The observations began at zenith distance = 86 deg. The sun altitude is -10.6 deg. The galactic latitude b = 52 deg., longitude l = 171 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2649113 We obtain a following upper limits.
