Fermi GRB 240527A: 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 GRB 240527A ( Fermi GBM team, GCN 36544) errorbox 54107 sec after notice time and 54125 sec after trigger time at 2024-05-27 22:09:31 UT, with upper limit up to 17.4 mag. The observations began at zenith distance = 66 deg. The sun altitude is -77.9 deg. The galactic latitude b = -29 deg., longitude l = 30 deg. Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2471879 We obtain a following upper limits.
