Me and a couple of buddies were out on the Guadalupe river last night when the area we were in lit up. Not even a few seconds before that were staring up at the stars since it was such a clear night. My best friend had said something so we all were looking at eachother talking when the everything lit up like lighting which we knew was impossible. So we look up immediately and I see a bright white light about an inch under the north star (almost the exact same size as the north star) and it just.. blew up? The white light turned into a ring of light expanding out from the center and I didn't see the trail but everyone of my buddies saw a smoke trail that was going through the ring and then it just disappeared.. we freaked out for a while. we felt so uneasy after it happened.
