		| Abstract: | 
		We present preliminary results of a study linking rotational period to photospheric surface activity derived from Doppler images. New Doppler images of 15 stars of spectral classification G to K, luminosity class III to V and rotational periods of 1.5 to 25 days have been computed. These Doppler images - along with previously published material - were averaged into latitudinal strips and their temperature distribution correlated with evolutionary status and rotational period. |
