Kathy Miles writes "The Leonid meteor shower is promising to be a 'once in a lifetime event.' It's not hard to photograph meteors, a simple 35mm camera that you can lock open the shutter on works fine. Here's complete instructions for 35mm, video and digital cameras.And, on the same site is information such as lore and myth, best way to watch meteors and times and skymaps for all US timezones. Happy Meteor watching!" And Geert Barentsen writes "As the adrenaline for the final Leonid meteor storm (November 19th) rises, one site seems to do a call to everybody to count the meteor activity and help science. With a few thousand meteors predicted per hour, it's going to be a busy night for true geeks :-)" Kevin Smolkowski writes "For the second year in a row, NASA will have Live Coverage of the 2002 Leonid meteor storm on Monday. Perfect for those of you surrounded by city lights. The all night show is hosted by NASA astronomers. They'll offer observing tips, answer phone calls from sky watchers, and tour the skies with a video camera located at the Marshall Space Flight Center (MSFC) in Huntsville, Alabama." Update: 11/18 22:40 GMT by T : McGravin writes "Everyone should also keep an ear on the extraplanetary visitors, too. I'm going to go add some ear-flaps to the tin foil helmet that protects my brain from them, so I can hear the meteors."

      It really IS this time. It's gonna be a big one, as the trail of comet debris (left kindly by Tempel-Tuttle, IIRC) that forms this shower is really, really close this year, and it won't be remotely as good for another thirty years or so after the debris trails start getting further away from the Earth's orbit. Not exactly once-in-a-lifetime, but still. I like meteors.

    I have done astro photos before and here is good tip when using a SLR camera:
    To avoid wobbling the camera as you press the cable to start the exposure, just hold up a sheet of black paper in front of the lens. After the cable is dangling freely, remove the paper. When depressing the cable, do the same.

    Also, for anyone with a Sony DV camera, the AE Candel Light mode works great for filming the showers.

      I fogged a lot of film last year with way-too-long exposures. When you get one of those persistant fire trails, it's time to close the shutter and advance the film. And a good fireball doesn't even have to be in-frame to do this, I had a few off axis sparklers that caused some major lense artifacts (although some of those turned out to be *really* good prints unintentionally). If the artifacting bothers your sense of purity, use a big lens hood.

    2. Re:Tip for Photography by ai0524 · · Score: 3, Informative
      You probably fogged the film by not covering the viewfinder. With an SLR camera light can get to the film from the viewfinder. This is not a problem when you take pictures normally as your eye keeps light out. However when making long exposures with a tripod this isn't true. You should cover the viewfinder with the proper cap or something else when making long exposures. The web site mention in the article about making exposures probably mentions this but I cannot reach it at this time.


      Have fun! Remember to take different exposures (exposure bracketing) to make sure that you get a good exposure. Expose one stop in both directions from the calculated exposure.

    However - for the Earth as a whole that is not true. If one of the meteors which broke off the comet is only 50 or 60 meters in diameter the result would be an impact similar to Tunguska in the last century; a 20 to 30 megaton blast capable of destroying a city and killing millions.

      Don't worry chicken little, with the Leonids you are really quite safe.

      For the Leonids (which is the subject of the article, after all), even a large meteor will burn up in the atmosphere. The Leonid entry velocity is 70 km/s. Because the composition is mostly ice, meaning the Leonids have a lower density (approx. 1) than a typical meteor, and because of the high velocity, the Leonids burn up very quickly (relative to a "typical meteor"). The Leonids maintain a nearly constant velocity as they enter the atmosphere, and nearly any size Leonid will burn up by ~85 km altitude at the lowest. A more typical meteor, moving at 20 km/s with a density of approx. 3 will both slow down as it passes through the atmosphere (if large enough, it will slow down to the terminal velocity of any body falling in the atmosphere, and basically be in "free fall"). And for a typical meteor, 100 metric tons at "source" will be 1 kg on the ground.
