In Astronomy SE Line of lights moving in a straight line, with a few following is the canonical close as duplicate target for questions about the likely seeing of recently deployed Starlinks that move in a straight line as they begin to disperse in phase along their orbital plane.
I'm sure there's a Python script to be written using Skyfield that could check Celestrak and find all Starlink TLEs and do this, but I wonder if there are now websites that users could be pointed to where you type in your lat/lon and it tells you when Starlink trains will be observable.
This would be really useful for edge cases where what the OP reports sounds like it might be a Starlink train but might not be. New users are often good about including date, time and location and so having an easy-to-use resource would be very handy to help answer and/or possibly close as duplicate the question.
Today's example in Astronomy SE just as an example:
- I witnessed a steady stream of falling stars slowly falling one after another this morning. What was it?
