Starlink Train — Is It Visible Tonight?
After every Starlink launch, a batch of satellites climbs together from a low ~300 km orbit to the ~550 km operational shell. During that raising phase the batch flies as a tight line — the famous Starlink "train" — visible to the naked eye at dawn and dusk. This page detects raising batches live from CelesTrak orbital data and computes exact pass times, directions, and elevations for your location, entirely in your browser.
The train effect is temporary: once the satellites reach altitude and spread into their orbital planes, the line fades below naked-eye brightness. When no batch is raising, the page says so honestly — and lights up again within hours of the next launch.
