Description:     An air plane with the Northern Lights in the sky.  Also know as the Aurora Borealis,
these lights are best viewed in the cold dark winter months.  The beautiful blaze of the
, or Aurora Borealis, begins when energetic electrically charged particles accelerate along the
magnetic field lines into the upper atmosphere, where they collide with gas atoms, causing the
atoms to give off light. The air lights up rather like what happens in a fluorescent light tube.  The
colors reflect gases, the most usual yellow-green color coming from oxygen. Red coloring is also due
to oxygen with a contribution from nitrogen and violet is due to nitrogen. The charged particles
originate from the sun, and it is the “weather” conditions on the sun that decide whether or not we will
see the
aurora.  The Aurora begins low on the horizon a faint glow of greenish light which forms an
arch, stretching lazily across the sky can be seen in the night.  Additional bands of light form and drift
overhead, slowly brightening to form giant curtains in the sky that slowly wave like a gentle breeze
blowing.  The bottom of the
Aurora curtain brightens with a reddish tint and ripples faster. Blues and
purples appear as the curtains pass directly overhead.  Bright points of light swirl like a pinwheel. The
entire sky seems to be full of color and motion of the
Northern Lights.  Then, after a few hours, the
lights fade into a warm green glow.
