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.STAMPAenArticle10.1051/0004-6361/2016282452-s2.0-84966290935000375318300118http://arxiv.org/abs/1603.01410v1https://www.aanda.org/articles/aa/abs/2016/05/aa28245-16/aa28245-16.htmlFIS/05 - ASTRONOMIA E ASTROFISICA
