CASPER, Wyo. — Casper and Natrona County were treated to a preview of the “Super Blue Moon” on Tuesday evening.
The moon was just over 98% full on Tuesday, and when it rises tonight, it will be the last full “Super Blue Moon” to be seen until January 2037, according to NASA.
NASA says that the term “supermoon” describes the full moon when it is closest to Earth. The “blue” refers to the rarity of the supermoon, not its color. It’s used to describe a second full moon in a calendar month, which usually only has one full moon, according to Axios.
Tonight’s full moon will start to appear on the eastern horizon in Casper at around 7:35 p.m., according to the The Photographer’s Ephemeris (TPE) app.
