I tend to think it wasn't a UFO. More like an atmospheric disturbance or some sort of energy/electrical phenomenom.
It was only a few flashes at first and then there was many nearly all at once. It would be a very unusual craft if it was one. But then I've seen a couple of unusual 'things' in the sky.
I'm thinking that this was electrical in nature. Like static electricity. It was a clear, dry and cold morning. The lights were very bright and crisp and just about some pine trees. I've never heard of it before but it may have been a field of static electricity built up around the pine trees and maybe the first rays of sunlight triggered them to spark in light.
Or a bunch of faeires were having some fun. =)
Unfortunately I was in my truck warming it up so I couldn't hear a thing. I wish I could have gotten pictures but historically I'm not very good at capturing fleeting shots of nature or ghosties. I tried capturing the Leonid meteor shower but didn't do well at all. And every time I try to capture a ghost on film I get pictures of everyday objects. Sigh.
