The AAVSO's visual light curve of the long period variable, Y Capricorni, indicates taht the published period should be approximately doubled, but the derived value is rejected because the data are poorly distributed, and two of the visual comparison stars are variable. Photographic data lead to a revised period of 411.76 days.
