Fermi trigger No 754492985: 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 GRB241128.56 (trigger No 754492985,20h 05m 12.00s , -50d 37m 01.2s, R=32.43) errorbox 18760 sec after notice time and 18796 sec after trigger time at 2024-11-28 18:36:17 UT, with upper limit up to 19.6 mag. Observations started at twilight. The observations began at zenith distance = 37 deg. The sun altitude is -13.3 deg. The galactic latitude b = -33 deg., longitude l = 348 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2687320 We obtain a following upper limits.
