A blue moon occurs about 41 times a century or seven times every 19 years. Normally, blue moons come only about every two or three years. In 2018, unusually, there were two blue moons in one year and only two months apart. The next monthly blue moon is on August 30/31, 2023. The next seasonal blue moon takes place on August 19/20, 2024. Since both of them happen in August, they are traditionally called sturgeon moons. The next time we will get two blue moons in a year will be 2037.
The blue moon is the second full moon in a calendar month. So, if a full moon occurs on the first or second of the month and the lunar cycle (as seen from Earth called the synodic period, 29.5 days), then another full moon will occur on the 30 or 31. The second full moon is called the blue moon. The moon isn’t actually blue; it’s just a name that arose in the 16th century. Blue meant something that was “impossible.”
The forecast for Millersville during the upcoming blue moon will be mostly clear, so viewers should get a clear view of the moon. Unlike next year’s total eclipse, where the moon will completely cover the sun, no special eyewear is required to look at the upcoming blue moon.
