Bright stationary disc of light in pre-dawnI get up early for work, and it is not unusual to take the dog out before daybreak. On May 10, I was outside with the dog at 5:15 am, waiting for her to finish up so I could get ready for work. I was looking at the sky to see what stars I could identify, but there were scattered clouds so I didn’t see many. I realized there was a very bright light behind one group of clouds and thought to myself that the moon was extremely bright. The clouds were low and as they moved past the bright light, what I originally thought was the glow of the moon was not the moon after all.I didn’t see any definitive shape, just a very bright light, like a spotlight, and I thought it must be a helicopter. It definitely wasn’t an airplane--it didn’t move. Then I realized for a spotlight to be that bright and that large, I should hear some sort of sound.While we do live a couple of miles from a freeway, at that hour of the morning, there is very little noise in the neighborhood. This morning was no different, and this was no helicopter.I looked out at the yard to see where the dog was then looked back at the sky—no more than 5-6 seconds had lapsed--and the light was gone.
