Forwarded from KI3O of NCDXA.  I thought this was interesting so passing it along.

JGREENBELT, Md. (NASA GODDARD) – In the three years since it first provided images of the sun in the spring of 2010, NASA’s Solar Dynamics Observatory (SDO) has had virtually unbroken coverage of the sun’s rise toward solar maximum, the peak of solar activity in its regular 11-year cycle.  This video shows those three years of the sun at a pace of two images per day.
 
SDO’s Atmospheric Imaging Assembly (AIA) captures a shot of the sun every 12 seconds in 10 different wavelengths.  The images shown here are based on a wavelength of 171 Angstroms, which is in the extreme ultraviolet range and shows solar material at around 600,000 Kelvin.  In this wavelength it is easy to see the sun’s 25-day rotation as well as how solar activity has increased over three years.
