As rare as a blue moon? Not this week, when the first blue moon since August 2012 will grace us with its presence on Friday evening.
With typical summer clear skies forecast for the Sacramento region, nothing should get in the way of seeing the celestial event.
A blue moon can refer to the second full moon in any calendar month, and the astronomical rarity occurring at the end of the week was preceded by a full moon on July 2. The next blue moon won’t occur until 2018, when there will be the even rarer occurrence of two blue moons in a single year – one on Jan. 31 and one on March 31. There will also be a total lunar eclipse on Jan. 31. Although every total lunar eclipse requires a full moon, Dec. 30, 1982, was the last time a blue moon was involved.
