dc.description.abstractWe have used spectrophotometric data from 9 HST orbits to eclipse-map the primary component of the RS CVn binary SV Cam. From these observations and SV Cam's HIPPARCOS parallax we find that the surface flux in the eclipsed low-latitude region is about 30% lower than computed from the best fitting PHOENIX model atmosphere. The flux deficit can only be accounted for if about a third of the primary's surface is covered with unresolved spots. Even when we extend the spottedness from the eclipsed region to the entire surface, there still remains an unaccounted flux deficit. The remaining flux deficit is explained by the presence of a large polar spot extending down to latitude 48 +/- 6 degrees.en
