"Rare Blue Moon Supermoon Shines Over Wisconsin: Essential Details"

The brightest supermoon of 2023 will be visible in Wisconsin on Wednesday night. A supermoon occurs when the Moon's orbit is closest to Earth at the same time the Moon is full. This specific supermoon will be the brightest of the year due to its proximity to Earth. Supermoons occur three or four times a year and always appear consecutively. A blue moon, which is when there are two full moons in the same calendar month, will not actually appear blue. The best time to view the supermoon is at moonrise or moonset, and there will be another supermoon on September 28.
