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.

Here we see a small flare and eruption produced by Active Region 12871 on Sep. 29, 2021. Although this activity was too weak to be classified, the same active region produced many larger flares as it traversed the solar disk beginning on Sep. 17. One of the largest was an M-class flare on Sep. 23 that was captured by IRIS here: AR 12871 decayed as time went on and produced today's movie shortly before it rotated out of sight.
