SpaceX is publishing the precise location of each satellite continuously. It's really cool actually; most satellite operators don't do this. The raw data is available at Celestrak here: https://celestrak.com/NORAD/elements/supplemental/

I'm using this data to power my site that shows when you can see Starlink yourself: https://james.darpinian.com/satellites/?special=starlink-lat...

That's a really cool piece of software dude! Will definitely use this in the future to show some friends the starlink satellites.

The overlay on a nearby Streetview showing where the satellite will likely appear, with a timeline-based trajectory, is especially impressive.

This site is awesome! Have you thought about extending it to check for the position of the ISS? I would assume that information is probably readily available, as well.

Thanks! Yes, it can track most of the other bright satellites in the sky as well, try the base page link: https://james.darpinian.com/satellites/

Wow, this is great. Thank you!

What's the difference between the SpaceX supplied TLEs and ones derived from other sources? More accurate? Updated more often?

> More accurate? Updated more often?

Yes. There's only one other (public) source, https://space-track.org/ which publishes tracking results from US military radars. But the tracking results aren't as accurate as the satellites' own telemetry data.

That "where" feature based on street view is really nice

This is really cool
