So, Saturday morning I was up early (about 3:45am Vancouver time) taking pictures of the constellation Auriga(as one does when one is up early on a Saturday morning), when a train of satellites passed through it.
I gather these are the SpaceX Starlink satellites that Elon Musk launched.
In the attached pictures they are a bit faint, but can be seen as a series of dashes crossing the picture diagonally from top left to mid-right.
