＊ はくちょう座SS星 ＊ Since its discovery in 1896 by Louisa D. Wells of the Harvard College Observatory, SS Cygni has undoubtedly been one of the most observed variable stars in the night sky. In the past century of notoriety, not a single outburst of SS Cyg has been missed. In this time, nearly 220,000 observations submitted by AAVSO observers across the globe have contributed to the monitoring of some 800 outbursts. Being the brightest of the stars of its dwarf nova class, there is no doubt that SS Cyg is a favorite of many observers. |
