Given the task definition and input, reply with output. In this task, you are given a text of many news articles seperated by special token "|||||". Your task is to summarize them.

Calculate what is the best location for viewing the upcoming meteor shower, what night do I need to go out, and how active is the shower expected to be. Calculate the meteor shower activity at your site. 
  
 The handy Fluxtimator below is a Java applet that allows you to calculate the expected shower rate for a given date and a given location. It also allows you to see the difference between staying downtown or moving out into the country side to a dark and clear location. All rates were calculated by taking into account the Moon light, but assume a transparent cloud-less sky and unobstructed field of view. The Fluxtimator is infrequently updated with information regarding newly characterised showers and meteor outbursts. Keep tuned! Important: Check if your time zone is correctly identified. In the U.S.A., Daylight Savings Time (DST) applies between the first Sunday of April and the last Sunday of October. Disclaimer: The duration, peak activity and time of the peaks are based on recent numerical models. However, note that the anticipated flux levels of each component, the time of the peak, and the particle size distributions are uncertain . So, allow yourself some time to wait for the shower to unfold. 
  
  
  
 What is the difference between "Downtown" and "Mountaintop?" 
  
 The difference between "Mountaintop" and "Downtown" is one of sky limiting magnitude. Primarily, large cities and towns tend to suffer light pollution from streetlights, which lowers the sky limiting magnitude, making it more difficult to see faint objects. The moon can be a particular problem. Although Moon light will lower the sky limiting magnitude everywhere, it will do so more in downtown where there is much more dust in the air. The Moon at given phase and height will cause a much brighter sky downtown than it will do high in the mountains. Best rates are seen from aircraft! Where should I go for best viewing?

 The applet was developed by Peter Jenniskens and Dave Nugent of the SETI Institute using publicly available models of cometary dust trails. Most data are summarized and explained in the book by Peter Jenniskens "Meteor Showers and their Parent Comets" (Cambridge University Press publisher). The user's location, the rotation of the earth, the position of the Sun, and the orbit of the moon are used to estimate local meteor rates. Who can use this applet? 
  
 This applet is freely available to anyone with a computer capable of running it. It is Java 1.1 compatible. Windows and Mac OSX : Internet Explorer 3.0+, Netscape Navigator 3.0+, Mozilla. 
  
 Mac OS Classic : Internet Explorer 3.0+. Netscape/Mozilla users may need to download the Mac OS Runtime for Java and/or this MRJ Plugin.

  ||||| Meteor shower August 2010 peak comes early Friday. Emanating from the constellation Perseid, the meteor shower could yield sightings in some locations of up to 75 meteors an hour. 
  
 The Perseid Meteor Shower viewed from the Laguna Mountains in San Diego County in California on August, 12, 2004. The meteor shower is caused as the Earth enters a debris field left over from the Comet Swift-Tuttle that occurred in 1862. The comet gets its name from the constellation Perseus since the meteors usually radiate from that location in the sky. 
  
 The annual Perseid meteor shower, one of the finest shows in August's night sky, is set to dazzle the bleary-eyed in the wee hours of Friday. 
  
 If you live under very dark skies or can travel beyond the sky glow of urban America, you can expect to see up to 75 meteors an hour, astronomers suggest. If you're hardy enough to be on a mountaintop, the number could reach 108 meteors an hour. 
  
 The best viewing locations will be in the Northern Hemisphere, with Southern Hemisphere sky-watchers limited to perhaps 30 or 40 events an hour at the shower's peak.

 Of more than 364 meteor showers on the roster kept by the International Astronomical Union, the Perseids turn in the most reliably decent show of the bunch. (But not all 364 on the roster have been confirmed as independent meteor displays.) 
  
 This year's Perseid show is poised to be above average. So give it up for 109P/Swift-Tuttle, the comet whose debris is responsible for the show. It swings around the sun once every 135 years, spewing dust and gas as it nears the sun and heats up. The comet's last pass was in 1992. 
  
 In mid-July, Earth began moving into Swift-Tuttle’s stream of dust. The debris "is a very old stream that has been building for a long time and is a very dense concentration of dust," says Peter Jenniskens, a meteor researcher at the SETI Institute in Mountain View, Calif. 
  
 Indeed, "if you look back at records from the Middle Ages, you can see that people in the Middle Ages were seeing the Perseid meteor shower," he says. 
  
 Swift-Tuttle originated in the Oort cloud, a vast spherical cloud of frozen leftovers from the solar system's formation some 4.6 billion years ago. Roughly 160,000 years ago, as Swift-Tuttle was passing through to the inner solar system, Jupiter captured it, sort of. 
  
 That event shrank the comet's orbit around the sun. But Jupiter's gravity was never able to draw Swift-Tuttle into its fold of truly short-period comets, which reappear on average every 20 years or less. Instead, the newcomer joined the likes of Halley's comet, which have orbital periods ranging from about 20 to 200 years. 
  
 To be sure, Swift-Tuttle crosses Jupiter's orbit with each tour through the solar system, Mr. Jenniskens explains. But Swift-Tuttle is stealthy: Jupiter is never close enough to the comet during those passes to significantly alter its travel path. 
  
 Each pass of the comet ever so slowly thickens the dust stream it leaves behind. 
  
 This year's display is unlikely to match last year's, when the shower had three peaks – one of which topped 200 meteors an hour. But the 2010 event is benefiting from two conditions that promise to keep the display above average. 
  
 First, it's happening during a new moon, which means faint meteors will not have to compete with moonlight for your attention. 
  
 Second, Earth will be passing through a denser patch of Swift-Tuttle's dust stream than usual, according to William Cooke, who heads NASA's Meteroid Environment Office at the Marshall Spaceflight Center in Huntsville, Ala. The main dust stream got a slight stir from Saturn, and we're also running into a patch of material the comet off-loaded in 1479, Cooke explains. 
  
 To get an idea of how the peak of the Perseids – and that of many other meteor showers – could appear in your area, head over to the "Fluxtimator." Select the meteor shower, nearest major urban area, viewing conditions, and date, and the graph will automatically adjust itself to give you the peak viewing time at your location and how many "shooting stars" you may be able to see. 
  
 One encouraging note, courtesy of the Fluxtimator: If you miss the show early Friday morning, plenty of meteors will still be visible at about the same times early Saturday morning. 
  
 The meteors appear as though they are emerging from a patch of the sky containing the constellation Perseus – hence the name. That constellation is high enough in the night sky by midnight Thursday to begin the show. 
  
 You can find detailed viewing tips, including pointers for taking pictures of the shower, at the American Meteor Society's website.

Your local weather permitting, the annual Perseid meteor shower should light up the skies in the wee hours tonight, reports the Christian Science Monitor. The usual caveats apply—like the further you can get from the lights of the big city, the better your show. Best bet is to start checking after midnight, but for specifics, the CSM points to this nifty tool from NASA in which you can plug in the biggest nearby city for peak viewing times. And if you miss tonight, try again tomorrow night.
