Leonid Meteor Shower 2002 193
Jacer writes "Adler press reports that 'approximately every 33 years the Leonid Meteor shower becomes a breathtaking meteor storm -- capable of illuminating the night sky with thousands of meteors per hour. Astronomers predict that the height of the storm over North America in 2002 could possibly generate 40 meteors every minute -- over 2,400 per hour!' Space.com has plenty of information available. I wanted to submit it early so you could plan ahead. It'd make for a long work or school day, but it's not something I'd care to miss."

I actually thought the same thing. The Leonide shower is a yearly event due to dust located on earths track. Now some years ago a comet passed on this track and released new dust (much dust), so it was really spectacular last year or the year before. This happens every 33 years. In China people really observed a meteor thunderstorn, like 3600 meteors/h. I've seen some great long-exposition photos. (no, you don't call it a shot
This year you should expect to see far less meteors, much closer to the usual "background" levels. Still it could happen that some dust was left on the track or has re-arranged so it'll be there exactly when your country is at night. I was very unlucky when I tried to observe the shower - for I slept and only saw 2 - but my wishes came true: girlfriend and job... but it took some long time to fullfill. So good luck with the shower then.

You're mistaken. That was the leonid shower of 2001 that rotates 33 years.
The truth is that there are 33 different leonid showers in the family, each of which peak every 33 years.
Although this leonid shower may be greatest show within 33 years for any leonid shower on this rotation, it's really meaningless. It's the greatest of all within the set, and the number of elements in the set is one.

Basically for every time zone. You see, as the Earth rotates on its axis, it is also orbiting the sun. Some part of the Earth has to be plowing headlong into the trail of dust. And that has to happen at either the "dawn" line or the "sunset" line (think about it.)
If the Earth spun the other way 'round, meteor showers would always be best just after sunset. But, sadly, I was not consulted during the design phase...
Now that's the general principle. In this case, astronomers are predicting two particularly dense sections of the dust trail, one intersecting Earth's orbit at dawn Europe, and another around dawn East Coast Americas. But even people not in these locations should see the best local view at about an hour before sunrise.

Last Leonid shower for donkeys' (Score:5, Informative)
As the comet Tempel-Tuttle approaches the Sun toward a May 2031 perihelion, it will pass within 1.5 a.u. of Jupiter in August 2029. This encounter will push the comet closer to the Sun and increase the distance between Earth's orbit and the comet's to 0.0162 a.u. -- their largest separation since 1733. Such a large gulf between the two orbits may preclude any substantial meteor activity for the year 2031, and for several years thereafter, when the next cycle of Leonid storms would normally be expected.
In examining this next Leonid cycle, McNaught has found three outlying dust trails that the Earth will approach in the years 2033 and 2034. "Unfortunately," he notes, "they are probably too distant for any reasonable chance of high activity."
There will be little improvement at the comet's subsequent return in 2065, for the separation between the orbits of the comet and the Earth will have diminished only slightly to 0.0146 a.u.
In 2098 the separation of the orbits shrinks to 0.0062 a.u. And in 2131, for the first time since 1633, the comet crosses our orbital plane slightly outside the Earth's orbit at a distance of 0.0089 a.u. Not until one, or both, of these remote years can our great grandchildren expect to witness a storm of Leonid meteors.
So get out there and see the damn thing. I'm in Northern Thailand, so not much hope for me :-(

American Literature Quiz -- Cormac McCarthy (Score:4, Interesting)
Quick, any fans of Cormac McCarthy out there?
What book of his set in the 19th century prominently features the Leonids in the first few paragraphs?
Answer: Blood Meridian.
Quite possibly the best American novel written in the second half of the 20th century. It's about a band of American mercenaries who go into Mexico to hunt up scalps for pay.
(It's also one of the eeriest and most violent American novels written -- heads getting lopped off, horses getting slaughtered, and a very weird, Ahab-like character called 'The Judge' presiding over everything.)
Anyway, the main character -- the Kid -- is born beneath the Leonids, and the infrequent meteor shower during the night of The Kid's birth makes for a very strange sense of forboding. That, and the fact that the Leonids come every 33 years -- very Christ-like, I suppose -- so the kid gets marked with this odd mixture of innocence, wisdom, and violence.
So I had no idea what the Leonids were, and after reading Blood Meridian, I thought it was something McCarthy made up. But a little research, of course, proved otherwise.
The strange thing about the Leonids -- and about the cycle of Halley's (sp?) comet (Mark Twain was born when the comet appeared, died when the comet next appeared) -- makes for some interesting moments in American literature.
My question -- finally get back on topic -- is this: when all these meteors are shooting through the sky, do they burn up in the atmosphere? Do some make it through? You'd think if there were that many, one or two would cause some serious damage.

- Have a good field of view because they will be all over the sky not just in the vicinity of Leo
- Do NOT concentrate at the spot where they will come from (Leo) rather about 40 degrees away, as odd as this may seem, the shooting stars around Leo won't leave a long trail (they will be coming towards you ) and you won't be seing much.

Looks like we are in line with the dust trails from the famous 1767 and 1866 showers, when "meteors fell like rain." So there's a tiny chance it could be a shower of historic proportions. And of course the computer model for this prediction is experimental, the shower can (and probably will) turn out to be a dud.

Also if you're going out in the middle of noplace and decide not to stay until dawn grab some reflective tape to attach strips to stuff you're taking with you like the Thermor or binocs. The full moon will give just enough light for the strips to be seen in the dark so you don't lose them when you set them down in the grass or something. Don't forget strips on your flashlights too. This seems counter intuitive until you set your flash down in the dark grass when its off and can't find it against until you sit on it.

While the moon is up, you will only see the brightest of the meteors, so don't expect anything like last year. Just hope and pray for a storm during the narrow moon set/twilight window.

Also if you're on the east coast, you will be very close to twilight. This is a blessing and a curse. The extra light means a little more interference towards the back end of the second peak (5:30 to 5:45 AM EST on Nov 19). But it also means that the moon (as good as full) will be very close to the horizon in the opposite direction from Leo at this time, so it will be easier to hide from your view with a mountain or even a grove of trees.

Yes, putting trees, or even a house between you and the moon might make a difference. Also, wish for very, very transparent - no haze or muck - sky. The more transparent the sky, the less moon light is reflected and the darker the sky will appear.

3. The Pleiades, also known as 'Subaru' or 'Seven Sisters', among other names. Very young, bright stars forming from gas disturbed in a supernova. With moderately powered binocs or a small telescope, one can see that the 'seven sisters' are just the brightest of hundreds of stars in an open cluster. An extended-exposure astrophotograph will show the clouds of bluish gas and dust still surrounding the stars.
4. My favorite - Orion, and the Great Orion Nebula. For viewers in the mid-northern latitudes, look for 3 stars in a straight diagonal line, almost due south at 3:00 am and about 2/3 elevated from the horizon to the zenith. Below those three stars (Orion's Belt) you should be able to find two dimmer stars in a vertical line (Orion's Sword) with a fuzzy patch in between (in darker areas). Good binoculars or a small scope will show one of the most beautiful sights in the sky!

The odds of a collision are fairly small to begin with, and it's possible to hedge that a bit. The main body of most large satellites (speaking only for the geostationary variety) is less than 2.5 meters on a side. The solar arrays are much larger, but that's solved by rotating them so that they're edge-on to the approach path of the meteors.
It would be much more troublesome for the ISS or something else big. But something big also has mass on its side, and most of the particles involved in a meteor shower are really, really small.
