Making Connections (August 15, 2007)

Over a period of four days (July 27 - 31, 2007) two active regions can be seen by SOHO communicating with each other magnetically. While the areas remained fairly stable, in that they did not generate any solar storms, the magnetic field lines of connection between them shift and sway most of the time. Like two magnets that sit near each other, the magnetic fields of the active regions share a dynamic interplay that is fun to watch. While we cannot actually see magnetic field lines, we can see charged particles in extreme ultraviolet light tracing the field lines above the surface of the Sun.
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.
