Fermi GRB 241115A: 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 GRB 241115A ( Fermi GBM team, GCN 38234) errorbox 2796 sec after notice time and 2828 sec after trigger time at 2024-11-15 14:05:33 UT, with upper limit up to 14.0 mag. The observations began at zenith distance = 83 deg. The sun altitude is -44.1 deg. The galactic latitude b = -14 deg., longitude l = 203 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2671089 We obtain a following upper limits.
