Visible ISS passes over Tianjin
The next visible pass over Tianjin starts on Sunday 1 November at 05:43 local time. The station appears in the north-west, climbs to 80° above the horizon and disappears towards the south-east after 10m 58s.

Visible ISS passes over Tianjin in the next seven days
| Date | Start | Peak | End | Duration | Max elev. | Path |
|---|---|---|---|---|---|---|
| Sunday 1 November | 05:43 | 05:48 | 05:54 | 10m 58s | 80° | NW → SE |
| Monday 2 November | 04:55 | 05:01 | 05:06 | 10m 56s | 59° | NW → ESE |
| Tuesday 3 November | 05:45 | 05:50 | 05:55 | 10m 17s | 25° | WNW → SSE |
| Thursday 5 November | 05:47 | 05:51 | 05:55 | 7m 58s | 8° low | WNW → S |
All times are local (Asia/Shanghai), 24-hour clock. “Direction” is where the station enters and leaves the sky. Only passes where the Sun is at least 6° below the horizon and the station itself is in sunlight are listed — the ones you can actually see.
The best pass of the week is on Sunday 1 November: it starts at 05:43 in the NW, peaks at 80° in the SW around 05:48, and is over by 05:54. That is the one to put a reminder on.
How to watch it from Tianjin
- Go out two minutes early. The station moves fast enough that a late start usually means you catch only the end of the pass.
- Face the direction in the table. On an ascending pass it travels roughly west-southwest to east-northeast; on a descending pass the other way round.
- No equipment needed. A bright pass looks like a steady white dot, brighter than any star, crossing the sky in about 10m 58s without blinking. Binoculars make it bigger but not more interesting.
- Give your eyes a minute. Look away from street lights and phone screens; the station is easy to see even from a city centre, but a dark spot makes the pass unmistakable.
- Watch the colour. Low passes near the horizon can turn orange or red as sunlight filters through the atmosphere — the same effect as a sunset, because that is exactly what you are seeing.
Why the ISS skips Tianjin for weeks at a time
Seeing the station needs two things at once: it has to be above your horizon, and it has to be sunlit while your sky is dark. The station orbits at 51.6° inclination, so from Tianjin (39.3° north) its ground track shifts west every orbit. For a week or two the evening passes line up with the twilight window and you get a run of good sightings; then the geometry drifts and the station is only up there during the day.
Chinese cities sit between 22° and 40° north, well inside the station's ground-track band, so the ISS often crosses close to the zenith — a pass can go from horizon to horizon in under six minutes. The limit is not height but twilight: at these latitudes the usable window is short and city light washes out the dimmer passes.
How these times are calculated
Every number on this page comes from the current CelesTrak two-line element set (TLE), propagated with SGP4 — the same model NASA and most tracking apps use — and converted to your local horizon with a full topocentric correction. The element set used here is from 29 October 2026, 13:31 UTC. A TLE is good for a few days; over a week the predicted times can drift by a minute or so, and a reboost of the station shifts everything by a few seconds. Check the live tracker on the day itself.

Questions
Can I see the ISS from Tianjin tonight?
Yes — the next visible pass is on Sunday 1 November at 05:43 local time.
How bright is it?
On a pass above 40° the station is typically magnitude −3 to −4, comparable to Venus and bright enough to be followed easily from a lit street. A 15° pass near the horizon is dimmer, more like a bright star, and easier to mistake for an aircraft — but aircraft blink and the station does not.
Does it make a sound?
No. At 400 km the station is far above the atmosphere you hear, and it travels faster than sound could carry anything towards you.
