"star" in an unknown to me, constellation started moving out of the "formation" and down, then another one went right to left.stepping outside to smoke a cigarette, looking up at the northern lights. noticed immediately a "star" moving slowly, down. it was coming out of what i thought was a constellation, im not sure what the constellation would be, but this "star" was the only one moving in the night sky. it went slowly, but constantly down, until out of sight behind a tree. waited for a couple of seconds thinking it might emerge, but no such luck. still wondering what it was, i looked around the sky, and to the right, another one started going from right to left, behind the same tree. i then pondered a minute what it might be, but i have no idea.
