Abstract
We present new observations of the cataclysmic variable V523 Lyr, a member of
the open cluster NGC 6791. The Kepler Space telescope obtained photometric
observations of this source and we examine the nearly 3 year long light curve.
The observations show numerous small amplitude outbursts recurring on average
every 33 days, intermittent quasi-periodic oscillations, and a significant
fully coherent period of ~3.8 hr which we identify as the orbital period of the
binary. Contemporaneous optical spectroscopy of V523 Lyr reveals a faint blue
source with broad Balmer absorption lines containing narrow emission cores.
H$\alpha$ is in emission above the continuum. The low amplitude of the
photometric signal and no detected velocity motion suggest a low orbital
inclination. We discuss the properties of V523 Lyr and show that it is a member
of the growing group of anomalous Z Cam type CVs, systems which show stunted
outbursts, light curve standstills, and occasional deep drops in brightness.
