Just as Active Region 792 was rotating into view on the left edge of the Sun, it fired off two substantial coronal mass ejections (CMEs) over a 30-hour period (July 28-30, 2005). A spectral line of singly-ionized helium at 304 Ångstroms shows the state of the solar plasma at roughly 60,000 C. Scientists have been awaiting this active region since it seems to have been the cause of a number of solar storms on the far side of the Sun. As it rotates further towards the center and right side of the Sun, it may well send a solar storm heading towards Earth. The resulting movie, captured at a high cadence of frames (which is uncommon for this wavelength) makes this one rank among the top five sequences taken in this wavelength.

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 steele.hill@gsfc.nasa.gov. |
