Side-by-side CMEs

July 16, 2013
Two CMEs (coronal mass ejections) expanded side-by-side into space in less than a day (July 1-2, 2013). The first and smaller of the two slowly emerged from the North Pole area of the Sun. The second and much larger, faster event, blossomed out to the left. Neither one was expected to have any impact on Earth. The images combine two coronagraphs from SOHO in which a disk covers the Sun to reveal the faint structures beyond it. The Sun in extreme ultraviolet light was imaged by SDO. Credit: NASA
