The Leonid meteor shower is forecasted to peak Monday afternoon (Nov. 17) in the U.S. eastern time zone, so stargazers in the United States are advised to look to the skies between midnight and dawn on Monday and Tuesday morning for the best view, astronomers say.
This year, the Leonid meteor shower should treat skywatchers to beween 10 and 15 meteors per hour, NASA meteor expert Bill Cook, head of the Meteoroid Environment Office at the agency's Marshall Space Flight Center in Huntsville, Alabama, told Space.com. For some meteor showers, that's considered a decent rate. [Photos: Most Amazing Leonid Meteor Shower Photos]
But the Leonids have a lot to live up to: In peak years, this meteor shower — which occurs every November — has produced meteors at a rate of 1,000 or more per hour. A year like that is unlikely to happen again for the Leonids until around 2034.
To have the best chance of spotting meteors, you should go to a location away from city lights, dress warmly, lie flat on your back and look straight up, Cooke said in a statement. No special viewing equipment is needed to see the Leonid shower; it can be seen with the naked eye.
The "shooting stars" from the Leonid meteor shower appear to come out of the constellation Leo, which will climb into view in the northern hemisphere after midnight. The meteors are bits of dust and rock from the tail of Comet Tempel-Tuttle, which does a loop around the sun every 33 years. Every November, Earth passes through the debris field left behind by Tempel-Tuttle, and the bits of debris "ram into the atmosphere at tens of thousands of miles an hour," according to StarDate magazine. The dust and rocks burn up in the atmosphere, creating the gorgeous light show seen on Earth.
Indoor viewing options
If skywatchers don't feel like going out in the cold, both NASA's Meteorite Environment Office and the Slooh Community Observatory will broadcast the shower live.
NASA's live stream will include a sky view from a telescope at Marshall Space Flight Center in Alabama. That stream will begin on Monday, Nov. 17 at 7:30 p.m. EST (0030 GMT Tuesday) and will continue until sunrise on Tuesday Nov. 18.
The Slooh live stream will begin on Monday, Nov. 17 at 8:00 p.m. EST (0100 GMT Tuesday) and will include more than just shots of the sky: Slooh will also broadcast audio of the "ionization sounds" created by the meteors. As the meteors streak through the sky, they briefly ionize the atmosphere. For a few seconds, the ionized region reflects short-wavelength radio waves, creating short blips and beeps of sound. Slooh's broadcast will also include interviews with astronomers.

Cooke noted that some astronomers have predicted that a second peak of this year's Leonid meteor shower will occur Thursday, Nov. 20. If those predictions are correct, skywatchers will see meteors created by debris left behind by Comet Tempel-Tuttle in 1567.
As the comet rounds the Earth, its debris field is stretched out by the gravity of Jupiter, Cooke said. Occasionally, the pull of gravity stretches portions of the debris into filaments, and this year, there's a chance Earth will pass through a filament of debris that is almost 450 years old.
