Broader View of Solar Outbursts (September 6, 2013)
Hi-res TIF (1.5M)
With the STEREO (Behind) Heliospheric Imager (HI), we can track the solar burst known as coronal mass ejections (CMEs) across a broad expanse of space stretching millions of miles (a 20 degree field of view). It is a wide-angle visible-light imaging system designed to detect CME events. This video clip shows several solar bursts of CMEs as they expand into space over one week period (Aug. 28 - Sept. 3, 2013). In these images, the Sun is just to the left of the frame and Earth is the bright object to the right (the downward line is a visual artifact). Credit: STEREO/NASA.
The images were taken by SOHO's coronagraphs in which a disk (black) blocks the Sun and some of the area around it so we can see faint structures beyond that. Here we superimposed the Sun from NASA's SDO. The movie covers about five hours of activity.
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 firstname.lastname@example.org.
