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.

A solar flare is an intense localized burst of electromagnetic radiation in different layers of the Sun's atmosphere. In this movie, IRIS captures a C-class flare in AR 13354 near the solar disk center, and it provides a fantastic close top view of various activities in the low solar atmosphere. In FOV fibrils spread over, materials flow along, loops brighten up, plasmas move up and fall back down, footpoints form several bright ribbon sections.
