Description:
Many positively charged area produced filaments because of the electrodynamic effect . All eruptions tend to this form. Without the supposition of the electric charge, we must suppose that these He II ions show a temperature of 60 000 K and the Sun has also a dynamo which rotates perpendicular to the equator (see loops on the limb with a direction of north-south). Many small areas of the surface (5778 K) shows the same colour as the eruptions. Note the clear coronal holes on the poles with filaments. (Courtesy of the SOHO EIT-team.
