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 magnetic field and the plasma in the solar atmosphere are coupled in an intricate way. The radiation from this magnetised plasma enables us to follow the complex evolution of the magnetic field. This movie shows the onset and aftermath of a small burst in the solar atmosphere. Each frame in this 80-min long movie is recorded at a high cadence of 3 s, facilitating a detailed view of plasma flows (as thin veils) from the burst. A portion of the neighbouring sunspot can also be viewed in this movie.
