Abstract

The old nova DQ Herculis is a cataclysmic variable with an orbital period of 4.65 hours and a spin period of 71 seconds. We used light curve data obtained from members of the Center for Backyard Astrophysics to make O-C diagrams and to update the orbital and spin ephemerides of the system. We discuss future plans for the data and possible sources of error with the data, as well as speculate long term variation in the orbital period.
