About this work
A large coronal hole stands out as the most obvious feature on the sun this week (Oct. 12-13, 2017). The dark structure, shaped kind of like the Pi symbol, spreads across much of the top of the sun. Though one cannot tell from this image and video clip in false-color extreme ultraviolet light, it is spewing high-speed solar wind particles into space and has been doing this all week.
