A friend and I observe an object for the past 10 months. We first noticed it by chance, talking and looking at the stars. It is in the same place, it has changed shape at times. Once going from a ball shape to having a spike shape bottom and then changing back. It does move and it has vanished before. We see it at about f8:30pm to about 3am. It does not scare us, but it has made my heart race a couple of times. We have noticed that it has appeared to flash colors and another object flashed back one night. This only occurred once but the other object also appeared to be on a straight line. Hard to explain, but clearly not a plane, helicopter, or star. It has skipped a few nights and approximate a month and a half, but other than that - every night!
