      fascinating universe is featured, along with a brief explanation
                    written by a professional astronomer.

   Most of the Sun is pictured peeking over a hill. On the surface of the
    Sun are several sunspots including a very large sunspot region toward
       the center-right. Please see the explanation for more detailed
                                information.

   Explanation: An unusually active sunspot region is now crossing the
   Sun. The region, labelled AR 4366, is much larger than the Earth and
   has produced several powerful solar flares over the past ten days. In
   the featured image, the region is marked by large and dark sunspots
   toward the upper right of the Sun's disk. The image captured the Sun
   over a hill in Zacatecas, Mexico, 5 days ago. AR 4366 has become a
   candidate for the most active solar region in this entire 11-year solar
   cycle. Active solar regions are frequently associated with increased
   auroral activity on the Earth. Now reaching the edge, AR 4366 will
   begin facing away from the Earth during the coming week. It is not
   known, though, if the active region will survive long enough to
   reappear in about two weeks' time, as the Sun rotates.
