Pulsing bright white lights, circle object in the night sky, moved in circles, up and down-left to right,went straight down disappearedLast night (8/7/11) my husband and son went to take the trash out at 10:30pm and he came back in and said you have to see this. I went to my front door and there was an object relatively low in the sky moving in circles and from left to right and up and down. What was most noticeable was that it was flashing a bright white light (like LED bright) but more of a pulse. You could see there was two lights (like headlights) and when it would face away you couldn't see the object. Then it would face us and get super bright. We watched it for a good five minutes. Then I tried to capture it on my cell phone video camera. You can see it move on my phone but its just a tiny dot. About a minute after I started filming it moved in a straight line down towards the mountain and we couldn't see it after that. My husband said it initially started out by our house and moved northwest to the location where I saw it. All I know is that it wasn't a plane or helicopter or anything I've seen before. The way it moved was unlike any aircraft I know of. I still cant stop thinking about it. It was so crazy.
