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 Swift GRB241113.33 (trigger No 1267501,01h 06m 18.24s , -22d 40m 01.2s, R=0.05) errorbox  36 sec after notice time and 876 sec after trigger time at 2024-11-13 08:02:50 UT, with upper limit up to  19.1 mag. The observations began at zenith distance = 77 deg. The sun  altitude  is -17.2 deg. 

The galactic latitude b = -84 deg., longitude l = 164 deg.
