This feed shows the Sun filtered to the wavelength of 171 angstrom. Images taken in this wavelength of light are useful for seeing magnetic arcs of plasma known as coronal loops. The brightest parts of the Sun's disc are where magnetic fields near the surface are strongest.

Compare this image to the magnetic field lines in the related feeds below. The multiview video lets you compare these views over the last week.
