The Solar Dynamics Observatory is open for business and man are the first light images amazing!!
Be sure to see the videos which are better-than-HD quality.
The sun will become more and more active as it the 11-year solar cycle swings from the slow and quiet to the loud and wild. You can follow along using some online solar observing tools. SOHO is still my favorite but Big Bear offers some excellent ground based views and the newer STEREO spacecraft has 3-D views and its own iPhone app!
