In a recent paper (Olah et al., 1985) we found that the active areas of UK Lac exhibited sometimes smali, sometimes large scale motions. In the case of the Sun it is well knovvn that new spots exhibit large proper motions while the old ones move almost together with the surrounding photosphere. On UK Lac both a newly formed active area and an existing old one showed rapid motions at the same time. A possible interpretation of this phenomenon is that new spots appeared in both the new and the old active areas simultaneously. This time coincidence may be aceidental, but if spots originate in dceper layers, than spots of common decp origin may appear in remote places of the stellar surface at the same time. Similar phenomena are seen on the Sun, when we observe simultaneous emergence of new flux in various parts of an extended active region (Zirin, 1983). The distribution of the active areas on the surface of HK Lac during the past eight years, is
discussed.
