The video below takes SDO images and applies additional processing to enhance
the structures visible. While there is no scientific value to this
processing, it does result in a beautiful, new way of looking at the
sun.
The original frames are in the 171 Angstrom wavelength of
extreme ultraviolet. This wavelength shows plasma in the solar
atmosphere, called the corona, that is around 600,000 Kelvin.
The
loops represent plasma held in place by magnetic fields. They are
concentrated in "active regions" where the magnetic fields are the
strongest. These active regions usually appear in visible light as
sunspots. The events in this video represent 24 hours of activity on
September 25, 2011.
