Auroras, Meteors, and Other Atmospheric Phenomena
rainbows, sun dogs, halos, and lunar and solar coronas

Auroras
• Auroras originate with the sun.
• Titanic explosions on the sun eject charged particles into space and some hit our planet.
• The particles cause the air to glow - what we call auroras.

Rainbows
• Rainbows are caused by rain drops in the air.
• These rain drops break light down into its many colors.
• When we see the reflected light, we see sun’s spectrum

Sundogs
• Sun dogs work much like rainbows, but the spectrum is caused by ice crystals high up.
• Six-sided ice crystals produce the spectrum and scatter sun’s light.

Halos and Coronas
• Halos around the sun an moon are nothing more than complete sundogs - or moondogs!
• Coronas are caused only by light scattering.

Meteors
• Meteors often arrive from space as meteor showers.
• Meteors are caused by debris from passing comets.
• The debris falls to Earth as a hot, shining streak.

Comets
• Frozen remains from the formation of our solar system.
• While not normally found in our planet’s atmosphere, comets can crash to earth.
• One probably did so in northern Russia in the year 1908.
