Watch the next Starlink train
A Starlink train is the dramatic "string of pearls" you see in the sky shortly after a launch, before the satellites spread out to their operational orbits. azmth automatically detects active trains by launch batch and shows their altitude and orbit-raising status. Enable your location to find out when the next train passes overhead.
Frequently asked
When can I see a Starlink train?
Trains are most visible in the first few days after a launch, at dawn or dusk. azmth detects currently active trains and predicts their passes for your location.
Why do Starlink satellites form a line?
They are released together into nearly the same orbit, so for a few days they travel in a tight evenly-spaced line before raising and dispersing to their operational positions.
