Visibility and prediction limits
Rise and set use the geometric horizon. Bearings run clockwise from true north: N 0°, E 90°, S 180°, W 270°. Visible intervals require elevation of at least 10°, the Sun at least 6° below your horizon, and a sufficiently sunlit station. A pass can fade into Earth’s shadow before it sets.
A dark sky alone does not mean the station is visible; a station can also be sunlit during the middle of the night. Clouds, local terrain, light pollution, station orientation, and brightness are not modeled. Seven-day estimates use SGP4 and should be rechecked near the pass, especially after maneuvers. Elements older than three days disable predictions.

The 3D paths are propagated orbits at the current Earth orientation, not surface ground tracks. Station markers are enlarged. Earth imagery: NASA Goddard Blue Marble, Reto Stöckli and Robert Simmon; this historical mosaic is not live weather.
