Spectroscopic and narrow-band photoelectric observations of the white dwarf eclipsing binary V471 Tau (= BD + 16°516) are reported. Periodic fluctuations in Ca IIH and K emission and Ha absorption, and a wave-like distortion of the light curve mimic the characteristics of several well-observed RS CVn binaries. A probable correlation between maximum emission-line strength and wave minimum is shown to exist.
