While in my backyard, I noticed moving white light in sky, which was clear with no clouds, and very dark out. This light was very bright and shiny, and moved overhead from a W/SW direction. I used my binoculars to see any details, but it just looked like a bright white light, somewhat spherical. As it tracked above my location toward the E/NE, it seemed to move in a slightly wiggling or erratic path. As I watched, it also seemed to slow down in its path. After about 2 minutes of viewing, I went inside the house to get a coat, and watch it from the front of our house. About 30 secs later as I went to front yard (thinking it would still be in sight), it had disappeared. I didn't behave or look like a high altitude satellite, which I've seen many times before. What was noticeable was its brightness and how close it seemed to the Earth (relatively speaking). I checked the location of the International Space Station, and the ISS was not above North America, so I don't think it was that.
