图2 两个Fireball

Two brilliant fireballs are among several meteors caught in one 3-minute shot. The brighter - estimated at magnitude -14, illuminates the clouds. This fireball at the bottom of the image, which appeared at 01.56 UT, is the same as that in the following closeup and the next, further shot, taken with a second camera. I was delighted to learn that the brighter fireball was also photographed by observers in Italy and other parts of France.

火流星和余迹
Three Leonid meteors streak through the constellation of Orion into Eridanus at the height of the great Leonid meteor storm of November 18, 2001.

Meteors are bits of debris ranging in size from grains of sand to small pebbles that are left behind by comets and burn up when they enter the Earth's atmosphere at high velocity.


The image was made at approximately 10:50 UT (5:50 am est) with an 85mm f/1.8 Nikon Lens working at f/2 on Fujicolor 800 negative film with a 5 minute guided exposure piggybacked on a telescope with an equatorial mounting tracking the stars to compensate for the Earth's rotation.

The colors in the meteor's path come from different emissions as the meteor burns up and interacts with molecules in the upper atmosphere.
