Flashing lights that approached each other and flew in a circle in Maine.At approximately 1:00 AM on August the 31st, 2008, a friend and I were watching the night sky and the shooting stars on Rocky Lake, which is in far eastern Maine. I noticed a flashing light up about 20 degrees in the sky to the left of the big dipper. Then to the right we noticed another flashing light coming towards and under the big dipper. The two flashing lights that were approaching each other became brighter as they got closer to each other. When they got to about 4 inches apart, as I saw them in the sky, they stopped (or dramatically slowed), became really bright, and began to do flash about randomly in a circle for about 5 seconds, in the space between where they stopped at and became bright at and each other. After that, two lights traveled from that point roughly back the same way as they came.As I saw the lights they were similar to the newer flashing lights of police cars that appear to randomly flash different colors yet there is a pattern if you look closer. I saw the lights as being connected, but flashing at separate places on the object. I did not have my camera on me and did not want to go back to my tent to get it at this point. After a few seconds we talked about what we had just seen. I was cold and went to the tent for my camera, binoculars and more clothing. When I got back I sat and watched the stars with my friend who was still there until it got too cold so I went back to my tent to sleep.
