Nacreous clouds

Current Temp Ambient:   -8   Windchill:   about the same (weather didn't post it for some reason)
Windspeed (knots):   calm, hurray!
Sunrise:    0735
Sunset:     1806



These are Nacreous clouds, a beautiful phenomenon seen only in extremely frigid, and typically polar environments.  These rare clouds exist in the Stratosphere (middle level of the atmosphere), as opposed to the Troposphere (lower level of the atmosphere) where normal clouds hang out (ha, get it, hang...).  They are something like 70k or 80k feet above the planet and the colors are amazing.  Nacreous clouds get light from the sun that has already set or has not yet risen and they are chemically different somehow, but I'm too lazy to look that up right now.  Here is a link to the wiki http://en.wikipedia.org/wiki/Polar_stratospheric_cloud.

I saw them on my way home last night, and on my way in to work this morning.  These pics are not blurry, that's just how the clouds look.

This place is sometimes like being on another planet...
