 Observers in portions of Mexico, Central America, southeastern Canada, the eastern U.S. and southern Europe will see the waning gibbous moon occult the bright naked eye star Aldebaran in the early hours of Wednesday (Oct. 19). The waning moon will cross in front of one of the brightest and most colorful stars in the sky on the night of October 18-19 for viewers in the southern and eastern United States, and part of eastern Canada. We'll be watching the Moon occult the bright star Aldebaran: https://t.co/Em6hvXH3typic.twitter.com/HBbZ5OxxfJ — Sky & Telescope (@SkyandTelescope) October 13, 2016 
 
 This so-called "graze line" is only a few hundred yards wide, but it runs right through Los Angeles and Denver, about 50 miles southeast of Las Vegas, and about 30 miles southeast of Minneapolis, Sky and Telescope says. A "grazing" occultation, when the star appears to slide right along the edge of the moon, is especially cool, asSky and Telescope notes: 
 
 "You'll probably see Aldebaran disappear and reappear several times in the darkness just barely off the moon's dazzlingly sunlit north polar region," the magazine said. YOUR TAKE: Share your photos of the night sky 
 
 These occultations of Aldebaran have been happening once per lunar month in a series that began in January 2015 and will end in September 2018. But most aren't visible in the U.S. 
 
 After this series ends, the next occultation of Aldebaran won't be until 2033.
– Sky watchers will get a bit of a show Tuesday night: People across the Eastern US and much of the Southwest will be able to see the moon move in front of Aldebaran, one of the brightest stars in the night sky, a phenomenon known as a lunar occultation, reports USA Today. Most in the viewing zone will see a "total occultation," in which the star disappears behind the moon. But the real treat comes for residents in certain areas of LA and Denver, who will be able to witness a "grazing occultation," where the star moves along the very periphery of the moon. Those with high-powered telescopes (or perhaps a nice pair of binoculars) should be able to see the star move in and out of view as mountain ranges and craters on the moon rise and fall. In the West, Aldebaran will disappear shortly after 10pm PDT, per Space.com. In the Eastern US, it will happen between 1am and 2am EDT. Astronomy site Sky and Telescope has the nitty-gritty on when and where to look.
