About High-Elevation Visible Passes: These are spectacular overhead passes when the International
Space Station crosses nearly straight above you (≥70° elevation). The ISS appears as an extremely bright moving
“star” – often the brightest object in the sky after the Moon. At high elevations, the ISS is visible for the
maximum duration and appears to move more slowly across the sky, making it easier to observe and photograph.

These predictions use N2YO’s visual pass algorithm which automatically filters for proper sun angles
(ISS in sunlight, observer in darkness/twilight).
