What is the Starlink “string of lights”?
When SpaceX launches a new batch of Starlink satellites, they're released together into a low orbit and spend the first days flying in a tight line before spreading out and climbing to their final altitude. During that window they look like a slow-moving string of evenly-spaced lights — often mistaken for a UFO. It's not a meteor or aircraft: it's sunlight glinting off a fresh Starlink train.
How to see it from Boston
- Time it for twilight — the train is only visible when your sky is dark but the satellites are still catching the Sun: roughly 1–2 hours after sunset or before sunrise.
- Look in the direction listed above — the line of lights rises near that horizon and drifts across the sky over 1–4 minutes.
- Get away from streetlights and let your eyes adjust for a few minutes.
- No equipment needed — a fresh train is easily naked-eye; binoculars make the spacing dramatic.
Want a closer look at what's overhead?
A pair of 10×50 binoculars makes the train's spacing pop, and a beginner smart telescope like the Seestar S50 or Dwarf 3 will image satellites, the ISS, and deep-sky objects from your backyard. See our 3-question picker.
