Abstract

SU Lyrae was discoverd to vary on plates taken in 1905. Over the years it has been classified as a nova, a dwarf nova (UG?), and recently as a Mira type. Over the last 30 years both the period and amplitude have appeared to change. I have inspected over 30 years of AAVSO data. This paper summarizes the results of my investigation.
