Abstract
We discuss the long-term quiescent light curve of the dwarf nova HT Ca ssiopeiae, with particular emphasis on the 1991-1995 behavior. HT Cas had no outbursts for at least eight years prior to a 1995 November 17 outburst. Its 1991-1995 light curve while in quiescence exhibits simil ar to 1.8 mag long-time-scale variations from about 15.9 to 17.7 mag. This is remarkable because dwarf novae while in quiescence have not pr eviously been described as exhibiting the kind of systematic high-stat e/low-state variations previously associated only with magnetic and VY Sd cataclysmic variables.
