Three years of Solar Dynamics Observatory images of the Sun — in three minutes.
I’ve posted the video below the fold. It’s quite cool.
Note that these images cover the period when the Sun was ramping up to what was hoped to be a strong solar maximum, when SDO was being designed and built. And though the Sun does appear to be active in these images, it is actually far less active than it has been for solar maximums going back at least a century.
