Helposti tulee ajatelleeksi, että MW-kelit paranisi (ja revontulet
vähenisi) piankin auringonpilkkumaksimin jälkeen. Tässä hieman jäitä hattuun:

Lähde: Swedx-lista/BOS/http://www.spacew.com/:

"The year with the maximum number of minor storm days is expected in
the year 2005 during the decline of solar cycle 23 when the occurrence
frequency of geoeffective coronal holes will reach a maximum. Over 40
minor storm days are expected in the year 2005. During the solar
maximum year of 2000, coronal mass ejection induced minor storms should
number at about 30 during the year. This is more than double the number
of minor storm days expected during 1997. Major geomagnetic storming is
expected to peak in the years between 1999 and 2002. Severe geomagnetic
storming, which is very difficult to predict, should peak in frequency
between the years 1999 and 2005 with the preferred year of peak severe
storm frequency being 2002."
