Abstract

(Abstract only) W Aquilae is a Mira-type long period variable with a published period of 489 days. A visual examination of recent light curves of this star indicates a change in the period of the star as well as an envelope suggestive of a much longer overall period. An analysis of visual observations from the AAVSO International Database from 1961 to 1998 is conducted using the DCDFT and CLEANEST algorithms.
