• Solar Mystery Nears Solution With Data From SOHO Spacecraft

Theoretical predictions for the structure and heating of the magnetic field above the solar surface using data for the magnetic data from MDI are compared to the heating observed by EIT. The white magnetic fieldlines eminate from the magnetic carpet and form arches from one magnetic polarity (white) to the other (black). Current theories predict that length and curvature of these arches determine the degree to which they are heated. The image underlying the arches is the heating observed at the same time by EIT in the Iron line at 195 Angstroms, with bright green corresponding to relatively hot regions and dark green corresponding to cool ones.
