In a matter of hours two large prominence eruptions occurred on the
Sun on January 21-22, 2003. The first and smaller filament was
located in the Sun's lower left quadrant and its eruption is
accompanied by a coronal mass ejection followed by a long cylinder of
post-coronal loops. Just hours later another long solar filament
(upper right quadrant) was observed erupting as it neared the Sun's
edge. The series of stills, taken by the EIT 195 instrument over a
six-hour period shows this prominence in profile before, during and
after its eruption. (Filaments are called prominences when they can
be seen in profile.) This particular prominence was over 50 times the
diameter of Earth, reaching almost half way across the Sun.
Prominences are cooler structures that "float" above the Sun's
surface, sometimes for several weeks. This one has been observed for
almost two weeks as it rotated around with the Sun. The video clips
show the full disk and a close-up of the second eruption over about a
one-day period. |

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.
