Abstract

 

New B and V observations of the variable-amplitude classical Cepheid HR 7308 are used to determine whether the change in amplitude is periodic.  It is shown that while the amplitude change is not simply periodic, it may be semiregular, with approximate elements of JD_max = 2447410 +1258 E.
