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 EP241208a ( EP Team et al., GCN 38513) errorbox 466 sec after trigger time at 2024-12-09 14:53:48 UT, with upper limit up to 20.0 mag. The observations began at zenith distance = 50 deg. The sun altitude is -52.9 deg.
The galactic latitude b = 37 deg., longitude l = 171 deg.
Real time updated cover map and OT discovered available here: https://master.sai.msu.ru/site/master2/observ.php?id=2702991
We obtain a following upper limits.
