Time lapse video of the Big Dipper, otherwise known as Ursa Major, shot on Tuesday September 3, 2019 between about 9:00PM PDT and 12:45AM PDT. The occasional light on the building on the left side of the screen is from the neighbors automatic light going on and off. If you watch closely you can see streaks from jets heading towards Sea-Tac airport in Seattle Washington. It was a very warm summer night when this time lapse was shot.
