ISS passes
Potentially visible ISS passes in the available forecast window: above 10° altitude, Sun below −6°, and a simple sunlight test. Clouds, obstructions and forecast changes affect visibility. Times are approximate to the nearest minute.

Before observing
Find an unobstructed view and check local weather. The bright planets listed here can be seen without a telescope when conditions allow. Never point binoculars or a telescope toward the Sun.
NASA skywatching guides ↗Sources and calculation method
Moon and planet positions use Astronomy Engine 2.1.19, with local horizon coordinates and atmospheric refraction. Elevations and horizon obstructions are approximate. ISS positions come from the published NASA orbital forecast; 30-second samples and a cylindrical Earth-shadow model identify possible visible intervals. A stale, incomplete or unavailable forecast produces no pass prediction.
