Good morning, Rallypoint. Today's Astronomy Picture of the Day (APOD) is titled "Green Flashes: Sun, Moon, Venus, Mercury." We aren't talking about obscure characters in a DC Comic series. This green flash is caused by refraction of light rays traveling to the eye over a long path through the atmosphere. Shorter wavelengths refract more strongly than longer redder wavelengths and the separation of colors lends a green hue to the last visible vestige of solar light at twilight: direct or reflected. Hence, it is more easily seen from the Sun. However, a skilled photographer (and one with the necessary hardware, like this one) can catch the green flash from other sources. So we have three other images to enjoy: the Moon, Venus, and Mercury. Quite well done, don't you think?

QUICKSILVER MESSENGER SERVICE - MAID OF THE CANCER MOON/CALGARY
INSTRUMENTAL. Very nice Soundboard Recording.
Thank you my friend Maj William W. 'Bill' Price for posting the NASA Astronomy Picture of the Day (APOD) is titled "Green Flashes: Sun, Moon, Venus, Mercury."

APOD background "Explanation: Follow a sunset on a clear day against a distant horizon and you might glimpse green just as the Sun disappears from view. The green flash is caused by refraction of light rays traveling to the eye over a long path through the atmosphere. Shorter wavelengths refract more strongly than longer redder wavelengths and the separation of colors lends a green hue to the last visible vestige of the solar disk. It's harder to see a green flash from the Moon, not to mention the diminutive disks of Venus and Mercury. But a telescope or telephoto lens and camera can help catch this tantalizing result of atmospheric refraction when the celestial bodies are near the horizon. From Sicily, the top panels were recorded on March 18, 2019 for the Sun and May 8, 2020 for the Moon. Also from the Mediterranean island, the bottom panels were shot during the twilight apparition of Venus and Mercury near the western horizon on May 24."
