The first 4 are from the local Aurora Boriealas on November 11th 2004 3:25am - 3:53am.

A couple sun sets. One in the Adirondacks, one local.

Instead of just the treetops - got a wider lens?

.... would have been the houses across the street. Ew. Thus the shots. I had no clue we would see it, I do not live THAT far north, haha. A friend called me as he left and said look out your front window, I grabbed the cam and went to town before it faded away.

It was a strong impact anyways, a very rare occurrence for us. Thanks anyway,

Told ya the houses looked terrible, anyways.

It went through a major change, which did not last long enough to capture with anything better than a snap shot.

Plus most of it was very high in the sky, pretty much aiming mostly straight up, until the quick ending.

The "Exposure bias" determines the gain to develop the RAW data. You can lighten or darken the image by using the exposure bias. It almost has the same effect as the "Exposure compensation" setting of other digital cameras.

Activity was suppose to be pretty high, and we had clear nights but couldn't afford to stay up late to look for them.

For those interested in northern lights, subscribe to aurora watch mailing list.
