Sun ‘artwork’ by the Solar Dynamics Observatory

If you check out the Solar Dynamics Observatory website today to get an update of what the Sun is doing, (which you should -everyday!) you may have noticed a few of the daily images appeared to be “sliding” across the screen. That’s because yesterday the team from the AIA instrument (Atmospheric Imaging Assembly) performed several instrument calibration maneuvers, in which the AIA boresight was moved away from the center of the Sun. When the images are re-centered some of them have lines to the edges of the picture, creating some very nifty solar artwork. Enjoy them now, as this effect will only show up in the “rapid” images shown on their website, and later, they’ll be corrected in the science database. See more below.
