Roswell, NM - 02-13-10

I was walking along Main Road, Roswell, on my way to find some dinner. I was walking in the direction away from the heart of Roswell.

At approximately 5.30 PM, I saw an object traveling through the sky, which at first I thought to be a balloon. It seemed to be as small or maybe a touch bigger than a balloon.

But as it came nearer I noticed it was not a balloon. It appeared greyish / metallic / aluminum in colour, and traveled at a good speed in a straight line though with a bobbing/rocking motion.

I took two photographs with my camera on full zoom. The camera is a Canon PowerShot S200. I could only take two quick snaps as my battery had died and I did not have a charger.

Any idea what this could be?
