"A substantial coronal mass ejection blew out from side of the Sun, giving us a great view of the event in profile (June 17-18, 2015). We caught the action in the 304 Angstrom wavelength of extreme ultraviolet light. The video clip covers about four hours of the event. While some of the plasma falls back into the Sun, a look at the coronagraph on SOHO shows a large cloud of particles heading into space."
