Abstract

 

A survey of Harvard College Observatory and Maria Mitchell Observatory plates was undertaken to clear up confusion surrounding the period of the 10th magnitude Cepheid, XY Cassiopeiae. New elements indicate a probable decrease in the period but do not confirm other period changes referred to in earlier studies.
