Fermi GRB 241030A: 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 GRB 241030A ( Fermi GBM team, GCN 37955) errorbox 36315 sec after notice time and 36349 sec after trigger time at 2024-10-30 15:53:52 UT, with upper limit up to 18.1 mag. Observations started at twilight. The observations began at zenith distance = 38 deg. The sun altitude is -14.6 deg. The galactic latitude b = 18 deg., longitude l = 115 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2653574 We obtain a following upper limits.
