Hey Greg, there's a good pass of the long starlink-4 "orange" group over Truckee this evening starting at 8:45 PM and running for more than 20 mins. Here's the ground track animation. Pink circle is the 10 degree elevation line:

Here's the sky chart of the lead satellite pass. All the others will follow almost the same path, 15-20s between sats. Its a pretty high pass starting over an hour after sunset so should be reasonably bright.

There's also a good (but not as bright) pass of the starlink-3 "gold" group before sunrise tomorrow morning. Here's an image of the pass start ground track map:

And the sky chart of the lead sat. This is 2 hrs before sunrise so will be plenty dark, and the sats will emerge from shadow and cross the summer triangle and southern milky way above Jupiter, Mars and Saturn. The moon will be up which will brighten the sky a bit, but I saw a pass early this morning at the same time from here in the burbs and they were easy to see. Try pointing a camera at the summer triangle and taking one or more long exps. Maybe get the planets in the same frame. I can't see them from my house - behind a hill.
