   aurora borealis, i. e., northern daybreak; popularly called
      northern lights. a luminous meteoric phenomenon, visible
      only at night, and supposed to be of electrical origin.
      this species of light usually appears in streams,
      ascending toward the zenith from a dusky line or bank, a
      few degrees above the northern horizon; when reaching
      south beyond the zenith, it forms what is called the
      corona, about a spot in the heavens toward which the
      dipping needle points. occasionally the aurora appears as
      an arch of light across the heavens from east to west.
      sometimes it assumes a wavy appearance, and the streams of
      light are then called merry dancers. they assume a variety
      of colors, from a pale red or yellow to a deep red or
      blood color. the

   aurora australisis a corresponding phenomenon in the
      southern hemisphere, the streams of light ascending in the
      same manner from near the southern horizon.
