X4 Flare was no Shrimp

March 11, 2014
An active region at the edge of the Sun blew out an X4 flare (one of the largest of the solar cycle) and a coronal mass ejection on Feb. 25, 2014. The still image of the ejected plasma (taken at 00:45 UT) shows it curled like a shrimp, but this eruption was no shrimp: it was powerful. The images seen here are a combination of two wavelengths of extreme ultraviolet light (171 and 304 Angstroms). The video clip covers about three hours of activity.
