When to see this Starlink train

For a few days to weeks after launch, these satellites fly close together and show up as a line of lights gliding across the sky, one after another. If you saw a string of lights moving together, it was most likely a fresh Starlink launch like this one.

These satellites have already climbed to their working orbit and spread out, so they no longer look like a train. Newer launches may still be in a line.
