i was sitting at my laptop and glanced outside the window to see the white sky it has been dumping snow. well i notice something that looked kind of like a giant black balloon or a blimp something you would see at a sports game. it was completely black had no light and was round. it was moving upward over the trees as it went over the trees it was moving downward.... i couldn't see anything after that.... i have no clue what i could have been...???
