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 sole sunspot of NOAA AR 12187 appears relatively quiet on this late October 2014 day, but all of a sudden it erupts, ejecting material for several minutes from two bright footpoints located in the sunspot umbra and at leading edge of the penumbra. Towards the end of this clip we can see some of the material falling down faintly again towards the sunspot.
