   Explanation: On a road trip up [5]Mount Uludağ in Bursa province,
   Turkey these motorcyclists found themselves above low clouds and fog in
   late June. With the bright Sun directly behind them, the view down the
   side of the great mountain revealed a beautiful, atmospheric glory and
   fog bow. Known to some as the [6]heiligenschein or the [7]Specter of
   the Brocken, a glory can also sometimes be seen from airplanes or even
   high buildings. It often appears to be a dark giant surrounded by a
   bright halo. Of course the dark giant is just the [8]shadow of the
   observer (90MB video) cast opposite the Sun. [9]The clouds and fog are
   composed of very small water droplets, smaller than rain drops, that
   refract and reflect sunlight to create the glory's colorful halo and
   this more extensive fog bow.
