DQ Her is one of the best studied Cataclysmic Variables. It is a classical nova which erupted in 1934 (Nova Herculis). Its optical lightcurve does not repeat accurately from one binary cycle to the next, but usually looks roughly like it does in Fig. 1. The small hump and small eclipse-asymmetry are probably both caused by the hot spot at the outer rim of the disk. The eclipse depth of ~90% argues for an inclination angle near 90°.
