Date: February 6, 2006
Time of Sighting: 1 AM PST
Date Reported: February 6, 2006
Duration of Sighting: 15 Seconds
Location of Sighting: Monroe, Washington (Northwest, Washington - About 25 Miles Northeast of Seattle)
Latitude: 47.85 Degrees North
Longitude: 121.95 Degrees West
Number of Witnesses: One
Weather: Cloud Ceiling 4,400 Feet. Light Rain. Visibility 10 Miles.  Winds gusting to 26 knots.

Description (In Witness's Own Words):  I saw the light in the Northeast sky heading towards Monroe on Highway 522.  This is the second time that I have seen this.  It was a bright blue flickering light in the sky. There was no way that it could have been lightning. The last time I checked lightning wasn't blue and besides this was a huge blue light.  I am sure that it was at least a few hundred yards wide. It was intense and lasted for about 15 seconds. The first sighting that I had I sent to King5 News via email. That one was MORE intense it seemed closer but lasted for a lot shorter period of time. Both times were incredible and mind blowing. I have never witnessed anything similar to this in the sky's before.

Investigator's Notes: The witness was impressed with his sighting. He reported the sighting within an hour of his experience.  Given that rain and quite stormy conditions were in the area at the time one could speculate that some type of electrical phenomenon could have been associated. However, as the witness stated lightning is not blue.  I also don't think the witness saw ball lightning. Power outages were reported in the area. Perhaps the blue light could have been the result of broken power lines.    Given available data I can't explain this sighting.
