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.

The Sun's activity turned up the heat over the Easter holiday, with active region AR14409 producing a series of flares and eruptions. Flares are usually rapid events, but on April 4, IRIS caught an M-class flare taking its time and unfolding with unusual patience. It seems that even the Sun likes to slow down over a long weekend.
