The candidate companion, ~50 times fainter than \\epsilon Cephei, if physically associated, is a late-type K or early M star, and lies at an angular separation of 330 mas, or 1.1 \\lambda/D for the WCS, making it the smallest angle detection ever realized with a coronagraph in terms of \\lambda/D units. The projected separation of the putative companion is ~8.6 AU, most likely on a highly eccentric orbit.
