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 EP241103a ( EP Team et al., GCN 38051) errorbox  1164 sec after notice time and 10420 sec after trigger time at 2024-11-03 04:18:17 UT, with upper limit up to  20.0 mag. The observations began at zenith distance = 51 deg. The sun  altitude  is -43.9 deg. 

The galactic latitude b = -41 deg., longitude l = 143 deg.
