Scientific paper

We present the BV light curves analysis of late-type, long-period stars 29 Dra, 12 Cam for the season 2005/2006, and shorter-period star II Peg for the same season. High latitude spots (alternatively spot configuration) cooler than surrounding photosphere were able to explain the light curves. The II Peg colour-index shift in H-R diagram is probably a consequence of stellar metallicity. Other associated mechanisms are briefly discussed.
