Moondog

When is a dog NOT a dog? When its a moondog!

I'd heard this term and never knew what it meant until Peter Ceren barked in about this piece on SpaceWeather.com. Thanks Peter!

MOONDOGS: When the moon comes beaming through your window tonight, peek outside. You might see a moondog. Betsy E. Bie photographed this one on Oct. 6th from a country road near Sheboygan Falls, Wisconsin.


Moondogs are created by ice crystals in high clouds, which refract moonlight into a rainbow-colored patch 22o from the Moon. The same crystals that make moondogs can also make moon pillars and spectacular moon halos. Keep an eye out for them, too!
