  Title: Aurora Australis, Sinuous Loop
  Description:
  This view of the Aurora Australis or Southern Lights (location unknown)
  shows  a sinuous looping band of airglow above the Earth Limb.  Calculated
  to be in  the 80 - 120 km altitude region, auroral activity is due to
  exitation of  atomic oxygen in the upper atmosphere by radiation from the
  van Allen  Radiation Belts and is most common above the 65 degree north and
  south  latitude range during the spring and fall of the year.
