Not the spacex starlink satellite since they were staggered (not in a straight line), spaced far apart and some going in different directions! we saw approx. 35 high altitude lights in the seattle area on 4/16/20 following a similar, staggered flight path with a fair distance between them moving south to north. during that same time period, we also saw approx. 10 high altitude lights going in different directions and some traveling side by side. this was around 9 p.M. and took about 20 minutes for all of them to pass over us.
