When To See A Rare ‘Blue Moon’ Rise At Dusk This Weekend

Key Takeaways

A Blue Moon is defined as the third full moon in an astronomical season with four full moons, occurring roughly every 2.5 to 3 years.
The Blue Moon does not actually appear blue; the term originated from a 19th-century misinterpretation of the Maine Farmers' Almanac, though rare atmospheric conditions like volcanic ash can cause a blue tint.
For best viewing, look east after sunset; the moon will appear full for about two to three nights, with peak illumination at 11:45 PM EDT on Saturday.
The next seasonal Blue Moon after this weekend will occur in August 2028, with the next monthly Blue Moon (second full moon in a month) happening in October 2031.

A rare Blue Moon will light up the sky this weekend, offering a stunning celestial show for stargazers across North America and the northern hemisphere. While the term 'Blue Moon' sounds magical, it actually refers to the third full moon in a season with four full moons, making it a relatively uncommon event that occurs roughly every two to three years. According to Forbes, the Blue Moon will rise at dusk this weekend, providing a perfect opportunity for moon-gazers to witness the spectacle. The best viewing times vary by location, but generally, the moon will appear full for a couple of nights, peaking on Saturday evening. Unlike the common misconception, a Blue Moon doesn't actually appear blue; the name originates from an old English phrase meaning 'betrayer moon,' though volcanic eruptions or wildfire smoke can occasionally tint it. This weekend's event is part of a seasonal pattern, with the next Blue Moon expected in 2028. For optimal viewing, find a spot with a clear eastern horizon, away from city lights, and look for the moon rising just after sunset. The Blue Moon also carries cultural significance, often associated with folklore and lunar calendars. This rare lunar event reminds us of the beauty and rhythm of the cosmos, making it a must-see for astronomy enthusiasts and casual observers alike.
