Abstract

Recent visual observations of the eclipsing variable EI Cephei indicate that one of the components may be an irregular physical variable with a range exceeding a magnitude. Both slow and rapid changes have been noted, and the star was well below normal maximum on all 48 nights of observation between January and April 1986.
