Ring Around the Moon

Picture credit: Chris Sprik

This ring around the moon is produced by the moonlight being reflected through 6-sided ice crystals in a thin uniform layer of cirrus clouds.

Beautiful blue skies today- remember that clear skies are produced by a high pressure system (clockwise rotation, sinking air). Amazing how fast the snow melts when there is an increase in the air's kinetic energy- ie: warmer weather.
