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) was pointed to the Integral GRB241013.04 (trigger No 10938,18h 21m 05.77s , -15d 37m 52.0s, R=0.05) errorbox  82668 sec after notice time and 82689 sec after trigger time at 2024-10-13 23:56:43 UT, with upper limit up to  16.4 mag. Observations started at twilight.  The observations began at zenith distance = 38 deg. The sun  altitude  is -15.8 deg. 

The galactic latitude b = -1 deg., longitude l = 16 deg.
