On Dec. 2, 1995 SOHO was launched into orbit aboard an Atlas rocket and a new generation of solar observing had begun. The Sun was near solar minimum and ten years later, almost an entire solar cycle, it approaches solar minimum again. The collage shows what we considered to be 30 of our most visually interesting images, but not all of our instruments are represented here.

To celebrate the achievement of these ten years of almost continuous observations, we have compiled a series of video clips, selected from each of the ten years of SOHO to showcase one aspect of our observations through a solar cycle. The frames for this series have been pulled from files in the SOHO archives (16 Terabytes), calibrated to the same color table, paced exactly the same, and in a few cases hand-corrected for the occasional dropped blocks of data. The movies show the Sun in the 195 Angstroms wavelength of extreme ultraviolet light. In essence you are seeing ionized iron at 1.5 million degrees in the lower corona of the Sun. Many people ask how long can SOHO go on? Until something goes really wrong, we could continue for many more years.

It may be worth noting that in a little over four years since the Weekly Pick began, it has received almost 9 million web hits. We sincerely appreciate the interest our viewers have shown in this feature of our web site.

Previous Picks of the Week

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.
