When SpaceX launches a bunch of Starlink satellites they are visible for a few days as a train of bright dots crossing the sky. They eventually spread out and boost themselves into higher orbits where they are not visible to the naked eye but will bug amateur and professional astronomers for decades as the photo bomb time exposures of celestial objects. We saw the train from the launch on September 1st at the BBQ Monday night. Another batch was launched on September 3rd and they were very bright last night. Higher elevation passes are the best as you can see from the iPhone video below as they passed across the Big Dipper in Ursa Major. The same bunch will be visible this evening and you can check this web page for details.
