Abstract

 

The B3-type eclipsing binary has a β Lyrae-type light curve of small amplitude. Betwen August 3 and November 24, 1978, 133 photoelectric observations of AH Cephei were obtained. A time of minimum derived from the mean light curve, JD (hel.) = 2442779.813 0.011 day, indicates the period may still be increasing.
