How to see the Starlink train tonight
Pick the right time
The best windows are 30–60 minutes after sunset or before sunrise, when satellites overhead are sunlit but your sky is dark.
Find a dark sky
Get away from bright lights with a clear horizon. A freshly launched batch is bright enough to see through light haze.
Know where to look
AstroSat shows which Starlink satellites pass over your location and when — direction and peak elevation included.
Watch it glide over
Newly deployed Starlinks appear as a straight line of evenly spaced lights sliding silently across the sky.
Starlink is SpaceX’s satellite-internet constellation — thousands of small satellites in low Earth orbit. When a fresh batch launches they fly bunched together before raising to their operational orbits, appearing from the ground as a striking “train” of lights. AstroSat renders the whole fleet live, computed in your browser with the SGP4 model from data refreshed every two hours, with pass predictions for your exact location.
Frequently asked questions
Can I see Starlink with the naked eye?
Yes — especially a freshly launched batch, which appears as a bright moving chain of lights after sunset or before sunrise.
Why does Starlink look like a train?
After deployment the satellites are still bunched close together before spreading to their final orbits, so they look like a straight line of evenly spaced dots.
When is the best time to see Starlink?
Roughly 30–60 minutes after sunset or before sunrise, when the satellites are sunlit but the ground is dark. AstroSat shows the exact pass times.
How do I find Starlink passes over me?
Open AstroSat, allow location access, and it lists which Starlink satellites cross your sky and when.
