MASTER-OAFA robotic telescope  (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L)  located in Argentina (OAFA observatory of San Juan National University) started inspect of the Fermi GRB241029.10 (trigger No 751861204,21h 37m 33.60s , +06d 35m 24.0s, R=1.2) errorbox  66 sec after notice time and 101 sec after trigger time at 2024-10-29 02:21:41 UT, with upper limit up to  18.6 mag. The observations began at zenith distance = 52 deg. The sun  altitude  is -37.4 deg. 

The galactic latitude b = -33 deg., longitude l = 62 deg.
