AIA 1600: This channel (as well as AIA 1700) 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: Transition region and upper photosphere
Wavelength: 1600 angstroms (0.00000016 m) = Far Ultraviolet
Primary ions seen: thrice ionized carbon (C IV) and Continuum
Characteristic temperatures: 6,000 K (11,000 ˚F), and 100,000 K (180,000˚F)
