Abstract

A study of the AAVSO data on the U Gem star AY Lyrae from 1935 to mid-1977 shows that it varies with a mean period of 23.7 days. It shows two types of outbursts: narrow-and-faint and wide-and-bright (supermaxima). A mean period of 205.5 days exists between supermaxima. NOTE: an erratum is published in JAAVSO (1978) Vol. 7, 110
