MOON RINGS -- 'AUREOLES' VS. 'CORONAS': Sometimes the best thing about a bright full Moon is what goes on around it. Last night in Pennsylvania, Dave Mitsky photographed this beautiful moon-ring:
The correct name is "lunar aureole," cousin to the better-known lunar corona. Aureoles and coronas are caused by water droplets in clouds. When the droplets are a jumble of different sizes, they produce a straw-colored ring--an aureole. When the droplets are all of the same size they produce a rainbow-colored ring--a corona. Look for both tonight.
