Flash in the sky with colors, it wasn't the northern lights.I was driving to work 5:13 am, when I saw a huge flash of light that lite up the entire sky, at first it was a teal blue/green then it changed to pink then purple back to a teal then dissipated. There was no sound. It lasted for about 6 seconds. You could clearly see the changing of colors. There were no beams...the whole sky lit up. I hope someone besides me witnessed this. The flash came from the North end of Cayuga Lake.
