Recent numerical modelling of mean field stellar dynamos with induction and Reynolds' equations show that, with increasing rotation, field symmetry changes from an axisymmetric solar type to a nonaxymmetric one, where the sc. active longitudes in the same stellar hemisphere are predicted to be of opposite polarities. It was originally named ``Active star Hale rule'' in Tuominen et al. (2002, AN, 323, 367), being an analogue to the famous bipolar sunspot polarity rule but different in scale and being a global phenomenon. In addition to long time series of temperature mapping and photometry, during the last few years we have been able to measure accurately polarization spectra of an active late-type star II Peg with the upgraded spectropolarimetric option of the high-resolution spectrograph SOFIN at the Nordic Optical Telescope, La Palma. The magnetic inversions can be compared to the dynamo models (Carroll et al., Kochukhov et al., this symposium) and the preliminary results show the theoretically predicted phenomenon happening.
