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.

Active region NOAA 13190 exhibited high activity in January 2023. On January 25, when it was located close to the western limb of the Sun from the perspective of the Earth, the active region produced a large eruptive M-class flare. The IRIS satellite observed remnants of this event; an arcade of extensive flare loops that formed during the flare. Later into the observation, plasma filling some of these flare loops endured cooling at which it started to pour down to the solar surface in the form of coronal rain.
