| Date | Start | Peak | End | Duration | Max elev. | Path |
|---|---|---|---|---|---|---|
| Wednesday 4 November | 17:55 | 18:00 | 18:05 | 10m 05s | 28° | NW → E |
| Friday 6 November | 17:32 | 17:37 | 17:42 | 10m 24s | 50° | NW → ESE |
| Saturday 7 November | 18:09 | 18:14 | 18:19 | 10m 10s | 34° | WNW → SE |
| Sunday 8 November | 18:46 | 18:50 | 18:54 | 7m 40s | 8° | W → S |
All times local, 24-hour clock. Only passes with the Sun at least 6° below the horizon and the station itself sunlit are listed — the ones you can actually see.
The best pass of the week is on Friday 6 November: rising at 17:32 in the NW, peaking at 50° in the NNE around 17:37, over by 17:42. That is the one to put a reminder on.
Why Tiangong is a good target from Hangzhou
Tiangong's orbit is inclined 41.47°, so its ground track never reaches further north than 41.5° latitude. Hangzhou sits close to that band, which is why the station regularly climbs to 70–90° here instead of skimming the horizon the way it does from northern Europe. A near-overhead pass is not brighter, but it is longer, crosses the whole sky, and is far harder to miss behind a building or a tree.
At around 100 tonnes it is roughly a quarter of the ISS mass, and peaks at magnitude 0 to +1 rather than −4: a steady, unblinking point, dimmer than the ISS but unmistakable once you know where to look.
How the times are calculated
Every number comes from the current two-line element set, propagated with SGP4 and converted to the local horizon with a full topocentric correction. The element set used here is from 01 November 2026, 00:08 UTC. A TLE stays accurate for a few days; reboosts shift the times by seconds, so check the live tracker on the day itself.

Questions
Can I see Tiangong from Hangzhou tonight?
Yes — the next visible pass is on Wednesday 4 November at 17:55 local time.
Is it brighter than the ISS?
No. The ISS reaches −4; Tiangong is about 0 to +1. What Tiangong has from China is altitude: more passes, higher in the sky.
Do I need binoculars?
No. Tiangong is a naked-eye object on any pass above ~30°; binoculars only make the dot slightly larger.
