I have been recording time lapse sunsets for years, with many on file. A week after filming a UFO at night over my house, I filmed a beautiful sunset from my house, pointed at the same patch of sky that the UFO flew over. As I watched the edited (time crunched) sunset video, I saw a number of planes, as usual.
After one low-elevation plane, there was a small circular object at a higher altitude, much higher than planes taking off from Seatac would fly. I’ve zoomed in on it best I can, and will attempt to film it again in the same part of the sky. There are things up there. This was filmed last Thursday, 2/20/2014 at 5:40PM, 4 miles NW of Seatac Airport.
