Abstract

(Abstract only) Novalike cataclysmic variables are often regarded as “constant” in their luminosity. However, evidence is mounting that they can vary by several magnitudes on longer timescales. Furthermore, in eclipsing systems the brightness of the system and depth of the eclipse appear correlated. I will show how AAVSO data can make very important contributions to this research.
