Summary

Using a more detailed geomagnetic activity Kp index, the finding in [3] that geomagnetic activity increases after the CMP of coronal holes, was verified; it was shown using individual activity patterns, that coronal holes apparently do not form a homogeneous class of phenomena, which must be respect in considerations of emissions of fast solar wind streams.
