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 when hot plasma cools and condenses in strong magnetic fields and falls to the photosphere. It is usually associated with active regions.[1][2][3][4][5][6] Coronal rain formed when impulsive heating from magnetic reconnection occurs.[7]
The material that makes up the coronal rain can be up to hundreds of times cooler than the surrounding environment.[8]
