Recent observations of the W Ursa Majoris System CN And reveal a large temperature difference (about 1500 K) between substantially overcontact components. The new light curves were used to improve the ephemeris and to provide photometric solutions of this system by the computer model of Wilson and Devinney. CN And is probably an example of an extreme overcontact configuration for a binary undergoing thermal relaxation oscillations, with components in poor thermal contact. This contention is supported by anomalous photometric activity roughly centered upon secondary eclipse. CN And is an excellent candidate for further spectroscopic, photometric, and theoretical investigation.
