Fermi trigger No 751616906: 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 GRB241026.27 (trigger No 751616906,15h 13m 43.92s , -15d 33m 00.0s, R=26.05) errorbox 42116 sec after notice time and 42149 sec after trigger time at 2024-10-26 18:10:50 UT, with upper limit up to 16.7 mag. Observations started at twilight. The observations began at zenith distance = 79 deg. The sun altitude is -15.1 deg. The galactic latitude b = 35 deg., longitude l = 347 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2649662 We obtain a following upper limits.
