If someone is trying to awaken some dark souls, tonight is night.
Halloween here (October 31), with the full “blue moon” – meaning the second full moon in a month. Full moons in the All Hallow night are rare, occurring every 19 years. But for the first time since 1944, hoax lined up with a blue moon, according to Farmer’s Almanac.
The spooky sky light show will start soon for the earliest candy hunters. Moonrise will happen between 5:50 and 6:40 pm local time across most of the United States, with some variance between different latitudes and locations in time zones. As soon as the moon rises, the moon will be visible on the horizon. As the night goes on, it will rise higher and shine more ̵1; illuminate any scammers out of the egg house (no, don’t do that!).

Much of the United States should have a night sky clear enough to spot a blue moon while going out, despite cloudy forecasts in New Jersey, New York and parts of New England, as well as the Pacific Northwest and central Minnesota, according National weather service.
The first full moon in October, which rises on the first day of the month, also has a special name: “Harvest Moon”, referring to the first fullness. moon after September feces. (Autumn’s second full moon, this blue moon, is sometimes named “Beaver Moon”, according to NASA.)
The Blue Moon (or Beaver Moon) occurs through frequent coincidence between the Gregorian calendar months and the regular moon phases. It’s a term that seems to originate in the 1940s, according to Sky and Telescope.
There is something special going on with the moon right now.
For one thing, it is at the farthest point in its orbit about 31,000 miles (50,000 km) away from the earth than its 239,000 miles (385,000 km) average. That makes this blue full moon also a “Micro Moon”, even though it looks only smaller than a “Super Moon” (it’s the Luna closest to Earth in its orbit).
More spectacularly, NASA researchers confirmed this month the presence of frozen water mines on the moon. Some were sandwiched between lunar dust particles. But for the most part it can exist in the form of vast frozen lakes, hidden in the darkest parts of deep craters, as Chelsea Gohd reported to Live Science’s sister site Space.com. And just a few months ago, researchers pointed out that tunnels may exist below the surface of the moon, large enough to accommodate an entire city.
One last thing to look for in the Halloween night sky: Mars. The closest Red Planet to Earth right now, even as humans approach more attentively than ever with probe and the plan for human missions to its surface. Right now, there are no humans up there. But sooner or later on certain Halloween, there may be tourists playing makeup on (or below) the crust of Mars.
