OrbitNight

Starlink train tonight

A fresh Starlink launch crosses the sky as a string of lights. Is one up there now, and when can you see it?

Trains in the sky now

No Starlink launch is flying as a train right now. A fresh launch stays lined up for roughly one to two weeks, then spreads out and is hard to see.

Next Starlink launch

Wed, Oct 21 · 7:14:00 AM · in 2.4 days

If it launches on time, a new train should be visible in the days after.

Pass alerts

You'll get a notification 10 minutes before a favorite satellite or a Starlink train becomes visible over your location.

Pick your location first, so we know when they pass over you.

Pass times are worked out in your browser, so your location is never sent to us. Alerts are planned 5 days ahead: open OrbitNight now and then to keep them coming.

When to look from your city

While a train is up, city pages list its passes next to the ISS.

What is a Starlink train?

SpaceX launches Starlink internet satellites in batches of about twenty to thirty. Right after release they fly one behind the other, low and close together, so they catch the sunlight as a line of moving dots.

Over the following days each satellite raises its orbit and the string stretches out. After a week or two they are spread around the orbit and much fainter.

We check every Starlink launch of the last month against its satellites' current orbits and only list it while at least half of them still fly within a few minutes of each other.

Seeing it

  • Like the ISS, a train is visible only after sunset or before sunrise, while the satellites are still in sunlight.
  • The first days after launch are the best: the line is tight and the satellites are low and bright.
  • The times cover the whole string, from the first satellite appearing to the last one fading.
