Happy Blue Moon Day! Tonight's full moon is the second within a calendar month. A rare occurrence by this definition, and others as well - all types are explained in this article of the Farmers' Almanac. https://www.farmersalmanac.com/blue-moon The moon will rise on the southeastern horizon just before 10:00pm EDT. It will be "full" (fully illuminated) at 4:45 am. Because it is at apogee, the farthest point from Earth in its orbit, this "micromoon" will appear smaller and dimmer than average. Although it won't actually be blue, it's still worth a glance before you turn in!
