July 22nd was tauted as the peak brightness for Comet LINEAR. However, as is the case along the Central Coast of California, haze, rain, or a marine layer will always get in the way.

This night was no exception. A forest fire in the northern part of the county contributed a haze layer which never did clear up.

LINEAR is a fast moving comet. The image above is an unguided exposure. You can see how much the comet moved in five minutes. The image below was guided on the comet's head; an unsuccesful attempt, though.

Compared to Hale-Bopp this comet was "truckin!"

Unsuccesful attempt to guide on the comet with a ST-4 autoguider. Five minute exposure using Fuji Color 800 film
