How to spot the ISS from Niigata
Niigata sits at 37.92°, 139.04°. The brightest passes typically appear within 1–2 hours of sunset and again before sunrise, when the satellite is sunlit while the sky above Niigata 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.
