How to spot the ISS from Tri-Cities
Tri-Cities sits at 46.25°, -119.20°. The brightest passes typically appear within 1–2 hours of sunset and again before sunrise, when the satellite is sunlit while the sky above Tri-Cities 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.
