Using a time series of high-resolution spectra and high-quality multi-colour photometry , we reconstruct surface maps of the primary component of the RS CVn type rapidly rotating eclipsing binary , SV Cam ( F9V + K4V ) .
We measure a mass ratio , q , of 0.641 ( 2 ) using our highest quality spectra and obtain surface brightness maps of the primary component , which exhibit predominantly high-latitude spots located between 60 ^ { \circ } - 70 ^ { \circ } latitudes with a mean filling factor of \sim 35 % .
This is also indicated by the R-band light curve inversion , subjected to rigourous numerical tests .
The spectral subtraction of the H _ { \alpha } line reveals strong activity of the secondary component .
The excess H _ { \alpha } absorption detected near the secondary minimum hints to the presence of cool material partially obscuring the primary star .
The flux ratios of Ca II IRT excess emission indicate that the contribution of chromospheric plage regions associated with star-spots is dominant , even during the passage of the filament-like absorption feature .
