White orb hovering slowly transitioning from white to red in color. Lasted for about 40 minutes.I work on the 19th floor in Seattle. I was sitting at my desk, I looked out the window and saw a glowing orb above Lake Union to the west, just hovering. After about 10 minutes of watching it completely still, it slowly started gaining altitude and moving to the east, bery slowly. Occasionally, I would lose sight of it, due to cloud coverage, but soon after the clouds passed, I would see it again, still moving very slowly and still gaining altitude. I would see it often turn from white to red. Not in a blinking fashion but in a very smooth transition from white to red. This total sighting lasted about 40 minutes. Then I lost sight of it.((NUFORC Note: We spoke via telephone with the witness, and she seemed to us to be a very responsible, sober-minded person. We suspect that she is a very reliable witness. PD))
