Azure Uranus and blue Moon: unusual features of the last eclipse

During the lunar eclipse on November 8, most observers saw how the Earth's satellite acquired a red hue. However, John Stetson of Sebago Lake, Maine, also saw another color—blue. Moreover, he captured this unusual tone in the photo.

The main part of the shadow from the Earth is red, since this zone is filled with sunlight scattered by aerosols in the atmosphere. For the same reason, sunsets and sunrises have a red color. However, the edge of the earth's shadow on the Moon turned out to be blue, since this area contains light that has passed through the upper layers of the stratosphere, in which ozone absorbs waves of the red spectrum and actually changes the passing light beam to blue. This is exactly what some observers have noticed.

However, in this case, this is not the only interesting phenomenon associated with the blue color. Thus, the azure disk of Uranus appeared from behind the moon during the eclipse. A resident of South Korea, Bum-Suk Yom, captured it in a photo using a 150-millimeter refractor.
