I'm living in kursk,russia.Today (01.01.2018) exactly 12 am we all celebrate new year in the place where we all celebrate all festival .We finished the celebration on the way to home, i and 2 others saw the light glow straight in the sky while walking .First i thought its a star and then it disappear.After some minutes it appears again changing direction upward and downward and disappeared again.Me and two guys witnessed it,let me know if anyone witnessed the same.
