Most months have only one full Moon. October 2020 has two, and tonight's full Moon is the second. According to modern folklore, that makes it a "Blue Moon." Of course, it won't actually turn blue ... unless it does. Major forest fires and volcanic eruptions can give the lunar disk a blue hue. If you see a truly-blue Moon tonight, keep in mind that it's a rare Halloween Blue Moon. Stay Tuned!
