NASA SDO - Transit of Venus, 193 Angstrom

AIA 193: This channel highlights the outer atmosphere of the Sun -- called the corona -- as well as hot flare plasma. Hot active regions, solar flares, and coronal mass ejections will appear bright here. The dark areas -- called coronal holes -- are places where very little radiation is emitted, yet are the main source of solar wind particles.

Where: Corona and hot flare plasma
Wavelength: 193 angstroms (0.0000000193 m) = Extreme Ultraviolet
Primary ions seen: 11 times ionized iron (Fe XII)
Characteristic temperature: 1.25 million K (2.25 million ˚F)

I wrote a book called Key West: Transit of Venus, so am always interested in seeing images of this event -- my book referenced the earlier transit in 2005.
