Blue Waxing Gibbous Moon 63% Solar Illuminated

Mountain Time 18:36
Almost directly overhead in my backyard in Tucson, Arizona, Southwestern United States, North America. It was a hazy day due to smoke and smog. I processed the image with Affinity's haze removal app on my PowerBook Pro computer.
Why Does The Moon Appear Blue?
The blue color of the dim areas of the moon is due to the scattering of reflected sunlight from the moon as it passes through the earth's atmosphere on its way to my lens. It is blue because the shorter wavelengths of white sunlight at 53 degrees Kelvin scatter more than the red end of the solar spectrum. The results are not too shabby.
