Fermi trigger No 752083996: Global MASTER-Net observations report

MASTER-SAAO robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in South Africa (South African Astronomical Observatory) started inspect of the Fermi GRB241031.68 (trigger No 752083996,17h 36m 16.80s , -01d 51m 36.0s, R=10.07) errorbox 6170 sec after notice time and 6206 sec after trigger time at 2024-10-31 17:56:38 UT, with upper limit up to 17.1 mag. Observations started at twilight. The observations began at zenith distance = 71 deg. The sun altitude is -11.4 deg. The galactic latitude b = 15 deg., longitude l = 23 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2654939 We obtain a following upper limits.
