Sequential Bursts (April 25, 2014)
Hi-res TIF (1.4M)
A single active region on the Sun ejected at least half a dozen bursts of plasma, several of clouds of which could be seen spreading across parts of the solar surface over two days (Apr. 19-21, 2014). These coronal mass ejections headed out into space as well, but in this movie from the ultraviolet imager on the STEREO (Ahead) spacecraft, we can see them spread out like a curtain above the Sun's surface. Remember that since STEREO is currently positioned to observe the far side of the Sun, these bursts would not be heading towards Earth. Credit: STEREO/NASA.
SOHO began its Weekly Pick some time after sending a weekly image or video clip to the American Museum of Natural History (Rose Center) in New York City. There, the SOHO Weekly Pick is displayed with some annotations on a large plasma display.
If your institution would also like to receive the same Weekly Pick from us for display (usually in Photoshop or QuickTime format), please send your inquiry to email@example.com.
