Abstract: We present new VRI photometry of V501 Aur obtained between 2007 and 2013 at the Grossschwabhausen (Germany) and Stará Lesná (Slovakia) observatories, as well as spectroscopic obervations from the Harvard-Smithsonian Center for Astrophysics (USA). The spectroscopic observations show it to be a single-lined binary, with a different period (68.8 days) than the one indicated by the photometry (∼55 days). We discuss the possible nature of the system.
