AIA 1700: This channel (as well as AIA 1600) often shows a web-like pattern of bright areas that highlight places where bundles of magnetic fields lines are concentrated. However, small areas with a lot of field lines will appear black, usually near sunspots and active regions.
Where: Temperature minimum and photosphere
Wavelength: 1700 angstroms (0.00000017 m) = Far Ultraviolet
Primary ions seen: Continuum
Characteristic temperature: 6,000 K (11,000 ˚F)
