Your Guide To Watching this Weekend's Halley's Comet Meteor ShowerRobbie Gonzalez5/03/13 3:22pmFiled to: SpaceAstronomymeteor showereta aquaridsciencehalley's cometearthgrazer96EditPromoteShare to KinjaToggle Conversation toolsGo to permalinkIn the early morning hours of Sunday, May 5, debris from Halley's Comet will light up the sky in this year's Eta Aquarid meteor shower. Here's everything you need to know to spot as many meteors as possible.Above: Halley's Comet, as photographed by NASA in 1986Halley's Comet won't make another appearance in our solar system for close to fifty years, but on its last visit, in 1986, it left some pieces of itself behind. Halley's cosmic litter has been making biannual appearances in the night sky ever since – once every October in the form of the Orionid meteor shower, and again every May, as the Eta Aquarids.AdvertisementBut here's the thing about the Eta Aquarids: their positioning in the night sky makes them almost imperceptible to skygazers in the Northern Hemisphere. While folks at southern latitudes can expect to spot between 50 and 60 meteors per hour, those of us north of the equator will struggle to catch site of meteors emanating from the constellation Aquarius, which will be hovering just above the Eastern horizon on Sunday morning. If you're north of 40 degrees latitude (say Chicago, or Philly), you're probably not going to see much of anything. South of that, and you're looking at between 10 and 20 meteors per hour, maybe more if you're lucky. So why bother with stargazing Sunday morning at all? According to meteor experts, you could spot something truly remarkable: an Earthgrazer.Skywatching expert Joe Rao explains over at SPACE.com:AdvertisementFor most, perhaps the best hope is perhaps catching a glimpse of a meteor emerging from the radiant that will skim the atmosphere horizontally — much like a bug skimming the side window of an automobile.Meteor watchers call such shooting stars "earthgrazers" and they are known for spectacularly long, colorful, long-lasting trails. "These meteors are extremely long," Robert Lunsford of the International Meteor Organization explained. "They tend to hug the horizon rather than shooting overhead where most cameras are aimed.""Earthgrazers are rarely numerous," NASA meteor expert Bill Cooke, a member of the Space Environments team at the Marshall Space Flight Center has said. "But even if you only see a few, you're likely to remember them." Is it worth it? We leave that to you to decide. If you live south of the equator you're in for one of the best displays of the year. If you're in a northern latitude, and you're up for it, here's your guide to spotting as many meteors as you can. Who knows – maybe you'll spot an earthgrazer.Avoid light like the plagueWe're talking all kinds of light. City lights, street lights, house lights, flashlights, any lights. Sunday's Moon will be a waning cresecent, so it shouldn't interfere too much, but there's still plenty of other ways to wash out the sky or effectively blind yourself. Seriously — don't blow it by checking your indiglo watch out of habit, and DON'T LOOK AT YOUR PHONE — it's a well-known fact that backlit cellphone screens were put on this Earth to ruin meteor showers.If you're in the country, go find a big open field. If you're in the city, get out if you can. If you can't get out, try to find a high point. (These measures can make a HUGE difference. The pictures featured above compare the night sky as seen from two points in Utah located just 75 miles apart. The difference? The bottom photo was taken in a major metropolitan area, the top photo a rural town. See more info here.)
