The Active Sun
Image for The Active Sun

Our Sun goes through an 11-year cycle (called the solar cycle) of activity where the number of sunspots varies.
Movie   ID   Title
Initial appearance of emission in 12-25 keV.   2463   RHESSI Observes the Flare over AR9906 - Rotate View Without Times
Last gasps of x-ray emission from this flare.   2462   RHESSI Observes the Flare over AR9906 - rotate view with times
RHESSI emission expands to an arc, apparently around the limb of the Sun.   2461   RHESSI Observes the Flare over AR9906 - zoom without times
Upflow viewed in TRACE appears at the center of the RHESSI emission.   2460   RHESSI Observes the Flare over AR9906 - zoom with times
Initial appearance of emission in 12-25 keV.   2459   RHESSI Observes the Flare over AR9906 - No time tags
TRACE emission brightens in RHESSI 12-25keV contours and new RHESSI emission at 50-100keV appears on the solar surface.   2458   RHESSI Observes the Flare over AR9906 - Time Tagged
Other field lines popping through the solar surface   2446   TRACE Observes the X-ray Flare Over AR9906
