Bright flashes of changing color light filled the sky.I was on my computer at my relative’s house in Port Orchard around 2:00am on January 5, 2009 and noticed outside that the sky had lit up like daylight but the whole sky had also lit up the color red. As soon as I noticed this I rushed to the window and the sky had already changed colors to blue or green and then was changing colors again, each color lasted about 2-3 seconds, and filled the sky completely, the entire thing lasted about 20 seconds. I had a clear view of the sky from the window and there was no visible cause for the lights. It was very cloudy outside however with a low lying cloud layer and lots of snow. I have read about a similar case of this happening in Melbourne, Australia, exact same details, so this most likely is a natural phenomena but I decided since I don’t know what it was I should probably report it. This could be fireworks reflecting off the clouds, except no sound of them, could be a low lying airplane with its lights reflecting off the clouds except again no sound of it. It could also be a meteor.
