METEOR SHOWERS OF 2007:

It's been cloudy and rainy here in Winnipeg for the last few days, and Molly missed the eta-Aquarid meteor shower whose best date was last night. Anyways, here's a list of the expected meteor showers of 2007. It is organized by name/best date/constellation/zenith hourly rate and origin. Enjoy watching if the skies are clear.

As you can see from the above list the most impressive meteor showers of th year are the Geminids, the Quadrantids and the Perseids. Of these only the Perseids occur in clement viewing conditions where you have to contend with mosquitoes rather than frostbite. The origin of most of the yearly meteor showers is unknown. Of those that are, one was produced by an asteroid and the others by comets. Comets are generally named after their discoverers, though it should be noted that the accepted names given above are actually often associated with a comet independently discovered by another whose name has been forgotten. There are brief biographies of Edmond Halley, Lewis Swift, Horace Tuttle and Ernst Temple at the Wikipedia site. A.E. Thatcher is a little more obscure. You can get the bare bones of his discovery at the site of the North American Meteor Network. If you are at all interested in exploring meteors in greater detail that site is the place to go.
