Аннотация:We present the results of our photometric observations of the eclipsing
dwarf novae V1239 Her, V2051 Oph, and EX Dra in quiescence. All light curves
exhibit a deep main eclipse, a depression near the secondary minimum, and a hump
before the eclipses. However, the light curves can vary from cycle to cycle. We have
improved the orbital period of V1239 Her using the O − C diagram over a long time
interval. The combined “hot line + hot spot” model was used to analyze the light curves
of V1239 Her. Some physical and geometrical parameters of the components, such as
the temperature of inner and outer disk and the hot spot, have been derived.
