International Space Station (ISS) viewing guide
Can I see the ISS without a telescope?
Yes. During a visible pass it looks like a bright, steady star moving quickly across the sky.
Why are some overhead passes not listed?
A pass is only listed when the ISS is sunlit while your local sky is dark enough.
How accurate are the times?
Orbital times are usually accurate to within seconds when current orbital elements are available. Recheck close to the pass because the orbit is periodically updated.
Data sources
Orbit data from CelesTrak using U.S. Space Force GP elements.
Weather forecast data from MET Norway (CC BY 4.0).
Orbit epoch: Aug 16, 2026, 4:19:22 AM UTC
