Meteors 2004
Uploaded 12/18/04
Something a little different for
this years meteor shower. For two nights we set up the Aurora
Cam and from 9pm to 5am on both nights, 48 images were taken
automatically. A 50mm f/2.8 lens was used which seemed more effective
than the 28mm at capturing the meteors. 4 meteors were recorded,
all near midnight. The ASA 800 Fuji Superia has poor reciprocity
failure, but high speed so was perfect for this type of work.
Three images of each meteor
are shown. The first is a clickable thumbnail for the full 1200
sized image. The second is a 100 percent crop of the original
scan to show the overall appearance. The third is a graphic profile
from top to bottom along the meteors path. Can you tell the meteors
direction from the path? Lets see...

Meteors start out dim,
gradually build and then burn up rapidly as they slam into the
denser parts of the atmosphere. So here, the meteor probably
went from right to left, or bottom to top in the image.

This one is very symmetrical
so no conclusions can be drawn from this one.

From right to left. The
slow increase, a few star spikes, and then a more rapid decline.
