Good morning, Rallypoint. Today's Astronomy Picture of the Day (APOD) is titled "A Lunar Corona over Turin." Seen in 2014 over Turin, Italy, the effect is created by the quantum mechanical diffraction of light around individual, similarly-sized water droplets in an intervening but mostly-transparent cloud. Since light of different colors has different wavelengths, each color diffracts differently and so becomes separately visible.

Good morning my friend Maj William W. 'Bill' Price and thank you for posting the NASA Astronomy Picture of the Day (APOD) for September 16, 2019 entitled "A Lunar Corona over Turin."

"Explanation: What are those colorful rings around the Moon? A corona. Rings like this will sometimes appear when the Moon is seen through thin clouds. The effect is created by the quantum mechanical diffraction of light around individual, similarly-sized water droplets in an intervening but mostly-transparent cloud. Since light of different colors has different wavelengths, each color diffracts differently. Lunar Coronae are one of the few quantum mechanical color effects that can be easily seen with the unaided eye. The featured lunar corona was captured around full Moon above Turin, Italy in 2014. Similar coronae that form around the Sun are usually harder to see because of the Sun's great brightness."

To learn more about corona please read thishttps://www.atoptics.co.uk/droplets/corona.htm
Good Monday Morning Maj William W. 'Bill' Price and thank you for this IMage of a lunar Corona... As I perused what is available I did find a short video clip of a Luna Corona, but not over Turin, Italy. It as taken by someone witnessing one of these luna corona's personally... It is interesting to watch... https://youtu.be/qwmYdAp2S3A
