The December 3rd supermoon, besides being the only supermoon in 2017, was the first of three successive full moon supermoons. The other two full moons will be on January 2 and 31, 2018. And, in fact, the full moon on January 31st is considered a Blue Moon because it’ll be the second of two full moons in one calendar month.
On January 2, the full moon distance from the Earth will be 356,846 at 2:24 UTC*, while the supermoon distance on January 1 will be 281 km closer at 356,565 km at 21:54 UTC*. (EarthSky)
Recently, blue moon refers simply to the second full moon which appears during a calendar month. In the past, the blue moon was the third of four full moon which appeared in a single season.
Although rare, sometimes blue moons are actually blue in color. A supermoon which rises after volcanic eruptions or major forest fires can have a blue appearance from the ash and dust particles in the air. “Clouds of water droplets, ice crystals or fine-grained sand can do the same thing.”(SpaceWeather)
At our hunting cabin, when I go outside during the early morning hours of winter — after the generator is turned off and there’s only an oil lamp lit for safety — I often see the “blue” of the moon and the millions of bright diamond-like stars and planets in the sky. It’s an awesome sight and one I’m so fortunate to be able to experience.
Hm-m! I wonder if residents of California will be seeing a blue blue moon during January?
May your New Year be happy, healthy and safe!
