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 EP241119a ( EP Team et al., GCN 38281) errorbox  244 sec after notice time and 48684 sec after trigger time at 2024-11-20 07:24:44 UT, with upper limit up to  19.2 mag. The observations began at zenith distance = 39 deg. The sun  altitude  is -22.7 deg. 

The galactic latitude b = -14 deg., longitude l = 201 deg.
