how sun spots may erupt

27 October 2014

At www.q-mag.org/understanding-and-forecasting-solar-eruptions.html … Anne Marie de Grazia has translated into English some French research in which they have followed the evolution of the solar magnetic field in a zone of eruptive behaviour. Their calculations show the formation of a magnetic cord which emerges from inside the Sun, becomes associated with a subsequent sun spot. They show the structure plays an important role in triggering CMEs – eruptions.

These eruptions are similar to well observed examples as seen via telescopes in the wider universe – sudden bursts of energy. The Japanese satellite Hinode was responsible for the images used in the French research and the paper can be read in Nature journal, Oct 23rd 2014.
