AIA 335: This channel (as well as AIA 211) highlights the active region of the outer atmosphere of the Sun -- the corona. Active regions, solar flares, and coronal mass ejections will appear bright here. The dark areas -- or coronal holes -- are places where very little radiation is emitted, yet are the main source of solar wind particles.
Where: Active regions of the corona
Wavelength: 335 angstroms (0.0000000335 m) = Extreme Ultraviolet
Primary ions seen: 15 times ionized iron (Fe XVI)
Characteristic temperature: 2.8 million K (5 million ˚F)
