Abstract:
    New differential UBV photoelectric photometry for the eclipsing binary
    AY Cam is presented. The Wilson-Devinney program is used to
    simultaneously solve the three light curves together with previously
    published radial velocities.

Description:
    Differential UBV measurements of AY Cam (BD+77 328, SAO 6527)
    were collected primarily during the 1976-1977 observing season, with a
    few additional nights in 1978 and 1981. The observations were made
    with an unrefrigerated EMI 6256S photomultiplier on the 0.9m telescope
    at the Fernbank Science Center (Atlanta, Georgia).
