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 241105A ( Fermi GBM team, GCN 38085) errorbox  6515 sec after notice time and 6547 sec after trigger time at 2024-11-05 17:55:11 UT, with upper limit up to  18.8 mag. Observations started at twilight.  The observations began at zenith distance = 64 deg. The sun  altitude  is -10.2 deg. 

The galactic latitude b = -47 deg., longitude l = 253 deg.
