The Orionid shooting star exhibitioner — one of the yr ’s most spectacular natural lighting shows — is upon us . This weekend , Earth will plow through a dense stream of supernal junk given off by Halley ’s Comet . These fragment of Halley will clash with the planet ’s atmosphere at focal ratio approach 150,000 miles per hr , go down the Nox inflamed as they blotch and burst across the pre - dawn sky of Saturday , October 20th and Sunday , October 21st .
Astronomers are predicting that Sunday ’s shower , in especial , will be one of the most impressive of 2012 . Here ’s everything you need to sleep with to discern as many meteors as possible .
Mike Brown ( the astronomer who killed Pluto ) likes to say that the Moon is his nemesis , because it dampen out his view of supernal body in the dark sky . And while you may not fit with Pluto ’s demotion , you ’d be saucy to take Brown ’s dictum to heart ; when you ’re bet for meteors , the Moon is your foe .
Fortunately , the Moon is n’t expected to be much of an issue at all this weekend . Not only will it be a climb crescent ( just five day past - Modern ) , it will also be entirely wanting from the pre - dawn sky . No Moon , of course , means no Moon to launder out the gleam of meteor blotch overhead .
But city lights , street light source , house lights , torch , any lights can be just as bad . Your surround will be giving off tons of the clobber , as will your personal particular — so do n’t be adrift your visual sense by checking your indiglo keep an eye on out of habit and for god ’s interest do n’t bet at your phone .

If you ’re in the land , go find a fully grown open field . If you ’re in the metropolis , get out if you’re able to . If you ca n’t get out , endeavor to regain a high point .
Taking all these matter into account can make a Brobdingnagian conflict . The images featured here help oneself illustrate the effect that light pollution can have on your stargazing experience . The bottom pic was taken in Orem , Utah — a major metropolitan area with around 400,000 people . The top photo was taken in Leamington , a rural Utah township , about 75 mile southwest of Orem , with a universe of just 217 people . The conflict in profile is staggering . Give it a little premeditation , and you may immensely ameliorate your experience ; theClear Sky Chartwebsite has a great lean of optimum viewing locations organized by state , so go assure it out .
Once you ’re all settled in at your meridian viewing spot , give your eyes at least 20 minutes to full adapt to the shadow . How do you roll in the hay if your eyes have adapted ? A good principle of thumb says if you may see all the star topology in the trivial bufflehead ( you should number 10 ) you ’ll see wad of meteors . If you ca n’t spot all 10 it ’s not a bountiful bargain , that ’s just under optimum stipulation .
The best hours for catch the Orionids will be between midnight and dawn on the mornings of October 20th and 21st . If you’re able to only be alert for one morning , make it the 21st — that ’s when activity is ask to peak .
you’re able to also useNASA ’s Fluxtimatorto assistance calculate the ideal time to direct your regard skywards . The Fluxtimator even takes your viewing location ( i.e. whether you ’re observe from the metropolis or the countryside ) and the luminousness of the Moon into account — just be certain to aline date and location information consequently .
As for where to calculate , that depends on who you ask . Some masses will tell you to look towards the radiant , where the shot stars will come along to exhale from ( for the Orionids this is near the configuration Orion ):
Bear in mind , however , that meteors ’ trails tend to be unretentive the nearer they are to the radiant . Your best bet is to probably just look straight up keep in mind that meteor can appear anywhere in the sky .
If you ’d care to conjoin local expert , snap here to find your region uranology baseball club , and find out whether they ’ll be setting up a telescope you may peek through with acquaintance . And if there ’s no local club , you’re able to alwaysjoin NASA ’s live , online chat about the shower .
Bring a reclining lawn death chair , a mantle , some pillows and a coat , as it ’s likely to get chilly . Basically , bring whatever you need to get comfortable and still keep your oculus on the sky . Do n’t seek to stand . Standing and looking up may seem like a seemly enough thought , but finally your neck will get stock , and the second you take your eyes off the sky is invariably when the bright meteors of the dark will go blaze by — it ’s like a code that all meteors subsist by .
You should n’t really involve a scope or binoculars , because you ’ll need to keep your eye on as much of the dark sky as possible . Bring something to nosh on , but nothing you have to expect at to rust . Hot coffee is always courteous . And eventually , impart some beneficial company , so you have somebody to “ ooh ” and “ ahh ” with while stargazing on this beautiful autumn Nox .
