MASTER-Tunka robotic telescope (Global MASTER-Net: http://observ.pereplet.ru, Lipunov et al., 2010, Advances in Astronomy, vol. 2010, 30L) located in Russia (Applied Physics Institute, Irkutsk State University) was pointed to the EP241202b ( EP Team et al., GCN 38426) errorbox 11695 sec after notice time and 68974 sec after trigger time at 2024-12-03 10:22:29 UT, with upper limit up to 19.5 mag. Observations started at twilight. The observations began at zenith distance = 78 deg. The sun altitude is -11.9 deg.
The galactic latitude b = -46 deg., longitude l = 175 deg.
Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2693898
We obtain a following upper limits.
