How to spot the ISS from Changshu
Changshu sits at 31.65°, 120.74°. The brightest passes typically appear within 1–2 hours of sunset and again before sunrise, when the satellite is sunlit while the sky above Changshu is dark. Look for a steady, fast-moving point of light brighter than most stars — the ISS rivals Venus at peak.
The table above lists every pass tonight reaching at least 10° elevation. Get away from direct streetlights for the best view; binoculars help but none of these passes require a telescope.
