~Leonid Meteor Shower~

November 21, 2015, 01:34:29 PM
November’s wonderful Leonid meteor shower happens every year at this time, as our world crosses the orbital path of Comet Tempel-Tuttle. Like many comets, Tempel-Tuttle litters its orbit with bits of debris. It’s when this cometary debris enters Earth’s atmosphere, and vaporizes, that we see the Leonid meteor shower. In 2015, the peak night of the shower is expected from midnight to dawn on Wednesday morning (November 18). The morning before that might be good as well. Although this shower is known for its periodic storms, no Leonid storm is expected this year. The waxing moon will set in the evening hours, so moonlight will not obstruct this year’s Leonid shower. Also, it’ll be fun to look for the bright planet Jupiter, which shines in front of the constellation Leo this year.
How many Leonid meteors will you see in 2015?
The answer of course depends on when you watch, the clarity and darkness of your night sky. This shower has been known to produce meteor storms, but no Leonid storm is expected this year. The Leonids are usually a modest shower, with typical rates of about 10 to 15 meteors per hour at the peak, in the darkness before dawn.
When should you watch for Leonid meteors in 2015?
Knowing what time to watch is easy. As with most meteor showers, the best time to watch the Leonids is usually between the hours of midnight and dawn. The expected peak morning is November 18. That’s the morning (not the evening) of the November 18. The morning before might be good as well. Fortunately, the waxing moon won’t jeopardize the view of this year’s Leonid meteor shower.
Where should you watch the meteor shower?
We hear lots of reports from people who see meteors from yards, decks, streets and especially highways in and around cities. But the best place to watch a meteor shower is always in the country. Just go far enough from town that glittering stars, the same stars drowned by city lights, begin to pop into view.
Which direction should I look to see the Leonids?
Meteors in annual showers are named for the point in our sky from which they appear to radiate. This shower is named for the constellation Leo the Lion, because these meteors radiate outward from the vicinity of stars representing the Lion’s mane.
If you trace the paths of Leonid meteors backward on the sky’s dome, they do seem to stream from near the star Algieba in the constellation Leo. The point in the sky from which they appear to radiate is called the radiant point. This radiant point is an optical illusion. It’s like standing on railroad tracks and peering off into the distance to see the tracks converge. The illusion of the radiant point is caused by the fact that the meteors – much like the railroad tracks – are moving on parallel paths.
In recent years, people have gotten the mistaken idea that you must know the whereabouts of a meteor shower’s radiant point in order to watch the meteor shower. You don’t need to. The meteors often don’t become visible until they are 30 degrees or so from their radiant point. They are streaking out from the radiant in all directions.
Will the Leonids produce a meteor storm in 2015?
No. Not this year. Most astronomers say you need more than 1,000 meteors an hour to consider a shower as a storm. That’s a far cry from the 10 to 15 meteors per hour predicted for this year. Still, even one bright meteor can make your night.
The Leonid shower is known for producing meteor storms, though. The parent comet – Tempel-Tuttle – completes a single orbit around the sun about once every 33 years. It releases fresh material every time it enters the inner solar system and approaches the sun. Since the 19th century, skywatchers have watched for Leonid meteor storms about every 33 years, beginning with the meteor storm of 1833, said to produce more than 100,000 meteors an hour.
The next great Leonid storms were seen about 33 years later, in 1866 and 1867.
Then a meteor storm was predicted for 1899, but did not materialize.
It wasn’t until 1966 that the next spectacular Leonid storm was seen, this time over the Americas. In 1966, observers in the southwest United States reported seeing 40 to 50 meteors per second (that’s 2,400 to 3,000 meteors per minute!) during a span of 15 minutes on the morning of November 17, 1966.
Bottom line:
If you want to watch the 2015 Leonid meteor shower, just know that the waxing moon won’t substantially interfere on the peak morning of November 18. The morning before, November 17, might be good as well. Find a dark sky location. Plan to watch between the hours of midnight and dawn. Bring along a blanket or lawn chair and spend at least an hour watching. Look for the planet Jupiter near the Leonids’ radiant point.

pretty sad though since this is normally seen in the northern hemisphere...

unfortunately...meteor showers are only visible in northern parts, north america, specifically Canada...though quite visible din sya in some parts of northern europe...but not as clearly and vivid as that from the northern hemisphere.
Thanks for passin by Sir Naruto...
