Storms in a Minor Key (May 11, 2007)
Hi-res TIF image(1.3M)
On May 9, 2007 two smaller coronal mass ejections (CMEs)burst out from the Sun. The first one headed to the left; the second, to the right, suggesting that they perhaps did not share the same source. Since CMEs of any visible size have been fairly rare over the past several months, the fact that we see two in one day is noteworthy. These were observed with our LASCO C2 coronagraph, one of two coronagraphs on SOHO. These are our best tools for observing solar storms in the corona. We continue to count on them, as we have over the past 11 years, to supply us with important information about the speed, power, and direction of solar storms. In this case neither of these storms was likely to produce any impacts on Earth.
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.
