See the ISS over Seoul

The International Space Station makes 12 visible passes over Seoul in the next few nights. Each one is a bright, fast-moving point of light crossing the sky in a matter of minutes — no telescope needed. Times below are in Seoul's local clock.

At 37.6°N, Seoul lies well inside the ISS's 51.6° orbital band, so the Station can climb almost to the zenith — its highest, brightest passes appear near straight overhead and can cross any part of the sky. Read why the ISS orbits at 51.6°.

Across the current forecast window the ISS makes 12 visible passes from Seoul: the best climbs to 71°, the brightest reaches magnitude −2.1 (bright), most appear from the NW, and they last about 6 minutes on average.

How to read this

  • Max height — how high the ISS climbs above the horizon at its peak, in degrees (90° is straight overhead). Higher passes are brighter and easier to spot.
  • Brightness — apparent magnitude; lower (more negative) is brighter. At its best the ISS outshines every star.
  • Appears → Leaves — the compass direction it rises from and sets toward. The station always tracks roughly west-to-east.

Frequently asked

When is the ISS visible from Seoul?

The next visible pass over Seoul is on Tue 21 Jul at 21:39 local time, climbing to 24° above the horizon. The station is only visible when it is sunlit and your sky is dark — around dawn and dusk — so favourable windows come in clusters of a few days, then disappear for a week or two as the orbit drifts.

Which direction should I look to see the ISS from Seoul?

For the next pass, look toward the NNW as it rises and follow it across to the E. The ISS always travels roughly west-to-east and crosses in two to six minutes — no telescope needed, it looks like a bright, steady star moving steadily across the sky. From Seoul, the ISS can pass directly overhead, so it may appear in any part of the sky.

How bright does the ISS get over Seoul?

At its best in this window the station reaches magnitude −2.1 (bright) — bright enough to outshine every star and most planets. The higher it climbs and the closer it passes to overhead, the brighter it appears.

Are these ISS pass times accurate?

Yes — they are computed from the latest published orbital element set (TLE) using the standard SGP4 model, the same maths professional tracking tools use. Times are shown in Seoul's local clock and refreshed continuously as a newer element set is published. For a live sky view and a phone-pointing AR mode, use the tracker on the home page.
