EP EP241026b: Global MASTER-Net observations report
Abstract
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 EP241026b ( EP Team et al., GCN 37902) errorbox 10998 sec after notice time and 48189 sec after trigger time at 2024-10-27 07:37:39 UT, with upper limit up to 18.5 mag. The observations began at zenith distance = 76 deg. The sun altitude is -25.1 deg. The galactic latitude b = -10 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=2650500 We obtain a following upper limits.
