Summary[edit]

Description
English: The most distinctive feature on the Sun this week was a good-sized coronal hole at a slanted angle nearly centered on the face of the sun (Oct. 31 - Nov. 2, 2018). Coronal holes are magnetically open areas from which solar wind particles speed into space. They appear darker in this wavelength of extreme ultraviolet light. If these particles impact Earth's magnetosphere, they will likely generate aurora near the Earth's poles regions. The video clip covers about two days of activity. SDO is managed by NASA's Goddard Space Flight Center, Greenbelt, Maryland, for NASA's Science Mission Directorate, Washington. Its Atmosphere Imaging Assembly was built by the Lockheed Martin Solar Astrophysics Laboratory (LMSAL), Palo Alto, California.
