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 EP241217a ( EP Team et al., GCN 38586) errorbox 26048 sec after notice time and 70566 sec after trigger time at 2024-12-18 01:12:09 UT, with upper limit up to 20.0 mag. The observations began at zenith distance = 63 deg. The sun altitude is -17.7 deg.
The galactic latitude b = -23 deg., longitude l = 155 deg.
Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2712866
We obtain a following upper limits.
