When will the International Space Station pass over Belfast?

ISS stands for the International Space Station — the largest and brightest human-made object in orbit around Earth. Passes over Belfast above 10° in the next 10 days: 43. Of those, visible to the naked eye: 10.

The next pass of the International Space Station over Belfast is on Monday 31 Aug at 01:36 local time, reaching 20° above the horizon. The next pass you can actually see is on Monday 31 Aug at 03:12 (45° above the horizon).

How to spot it

Look for a bright, fast “star” that doesn't blink — the ISS outshines everything except the Moon and Venus.
It moves west to east, crossing the whole sky in 3–6 minutes.
Evening and pre-dawn passes are the visible ones — the station must be sunlit while your sky is dark. Daytime passes in the table are invisible to the eye.
Belfast is outside the ISS's ±51.6° orbital band, so it always appears toward the horizon rather than overhead.
