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.

In this video of Active Region 13102, we see a series of micro flares go off over the course of about four hours, until finally the region brightens rapidly in a much larger M1.0 flare. This flare was co-observed by the Swedish Solar Telescope (SST), a ground-based telescope in the Canary Islands. SST studies the Sun in visible light, which provides complementary information to IRIS's ultraviolet observations.
