Happy Anniversary SDO!

Ten years ago, 11 Feb 2010, SDO rose majestically into the Florida skies. Since that day we have taken and recorded over 350 million images of the Sun.
Here's the image closest to the launch time, a lovely 211 Å image showing a large coronal hole over the South Pole and a smaller one over the north. Pretty typical solar minimum portrait!

Over the next year, Solar Cycle 25 will become more and more apparent. SDO will be there, observing the Sun and its magnetic field.

Congratulations to the SDO teams and all the people who enjoy our data!
