Aurinkopilkkujen rytmi so auringon aktiviteetti osuu yksiin sen kanssa kun venus, maa ja jupiter ovat samalla linjalla. Teorian mukaan planeettojen aiheuttamat vuorovesivaikutukset auringon kaasukehässä ovat pilkkuja rytmittävä mekanismi.
Jossain määrin mielenkiintoista mutta ei toki riitä astrologian selitysmalliksi.
Researchers discovered that the tidal forces of Venus, Earth and Jupiter influence the Sun’s magnetic field, thus governing the solar cycle. ... The scientists systematically compared historical observations of solar activity from the last thousand years with planetary constellations, statistically proving that the two phenomena are linked. ... planets are able to displace the hot plasma on the sun’s surface. Tidal forces are strongest when there is maximum Venus-Earth-Jupiter alignment; a constellation that occurs every 11.07 years.
