Active region (AR 1429) returned but not nearly the behemoth it was four weeks ago

The active region (AR 1429), the source of many strong flares and geomagnetic storms in the beginning of March 2012, has completed its journey around the Sun and is peaking over the Eastern limb of the Sun. But it is not nearly the behemoth it was four weeks ago.

The view through the HMI telescope shows the movement and development of this sunspot in early March and shows how this region is returning the end of March.

The AIA 171 angstrom view shows the coronal loops, arcs extending off the Sun where plasma moves along magnetic field lines. This video also includes a view of early and late March 2012 activities.

As the saying goes - "A trip around the Sun can make you decay...".
