Abstract

First Doppler images are presented for the giant component of the RSCVn-type binary ζ And from 1997/98. Polar spottedness with several high latitude features are restored with a temperature contrast of about 800K from all the three mapping lines available, while only weaker features are recovered at low latitudes. Photometric behaviour and the effect of ellipticity are discussed briefly.
