A movie of the coronal rain (right limb of sun) in the 304 Å wavelength. The footage in this video was collected by the Solar Dynamics Observatory's AIA instrument. SDO collected one frame every 12 seconds so each second in this video corresponds to 6 minutes of real time. The video covers 4:30 UTC on July 19th to 2:00 UTC on July 20th, a period of 21 hours and 30 minutes.

Coronal rain is a phenomenon that occurs in the sun's corona. It occurs when hot plasma in the corona cools and condenses in strong magnetic fields, usually associated with regions that produce solar flares. The plasma is attracted to the magnetic fields where it condenses and slowly falls back to the solar surface.[1][2][3][4][5][6]
