IRIS Movie of the Day
At least once a week a movie of the Sun taken by NASA's Interface Region Imaging Spectrograph (IRIS) is posted by one of the scientists operating the instrument.

This IRIS observation of AR12443 on 2015-November-04 shows the evolution of a solar flare in the chromosphere. The M3.7 flare shown here was associated with a global wave in the solar corona, and the bright lines seen here snaking across the field of view show the footprints of hot loops during the solar flare. This particular active region was near Sun centre as seen from Earth, and this eruption produced space weather effects near earth.
