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 GRB241113.20 (trigger No 753166198,08h 40m 31.20s , -50d 26m 24.0s, R=1.03) errorbox  76 sec after notice time and 114 sec after trigger time at 2024-11-13 04:51:47 UT, with upper limit up to  19.4 mag. The observations began at zenith distance = 55 deg. The sun  altitude  is -40.4 deg. 

The galactic latitude b = -5 deg., longitude l = 269 deg.


Real time updated cover map and OT discovered available here:
