Scientific paper

Stellar surface maps can be obtained from high resolution, high signal-to-noise spectra using Doppler imaging techniques. In this work we present new surface temperature maps of the giant FK Com for 2004-2007, and combine them with our earlier maps. The detailed images of the stellar surface span now almost 15 years. Together with the photometric observations this unique time series is used to study the spot evolution, spot life times, and possible permanent active longitudes on FK Com.
