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.
Bead-like bursts and a minor flare

A large active region (AR12672) on August 31st, 2017, still bursting with activity: from blinking bead-like UV bursts and brightening loop-like structures to a minor (B-class) flare closer to the limb, all captured in great detail by IRIS. This movie shows the diverse scales and complex structures in which the Sun releases energy, heating plasma and accelerating particles in the process.
