Biright flash in the sky.I was driving down the 15 freeway, me and my girlfreind suddenly saw a bright blueish white flash just above the clouds, it left a trail and then it was gone. It didnt seem like a comet or anything of that nature. To me it seemed strange only because there was still plenty of light in the sky. It could have been a shooting star, but there was reporting of lights in the sky the day before.I guess we'll never know. Just thought i'd report just in case nobody else did.
