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
