In view from you
Nobody watches Shiyong Tongbu Tongxin Wx. go over, but a receiver still asks whether it is above the horizon. Say where you are and this card answers.
Your position is rounded to about a kilometre and sent only to the Orbinauts API, to find the pass.
No brightness has been published for Shiyong Tongbu Tongxin Wx., so it is not a naked-eye satellite and no city page carries pass times for it. Nothing here estimates one.
Seeing it
There is nothing to go outside for: it is too faint for the naked eye. What reaches you from it reaches a dish or an antenna, not an eye.

No operator publishes an ephemeris for Shiyong Tongbu Tongxin Wx., so every position here comes from its orbital elements.
In orbit
- Close approaches
- 1 reported. No close approach to Shiyong Tongbu Tongxin Wx. is reported for the next three days.
From Space-Track’s public conjunction messages; the latest report was issued Nov 8, 2026, 2:43 PM, 9 hours old. Only approaches serious enough to be reported publicly are listed: within three days and, for two bodies near the Earth, closer than a kilometre with a chance of a collision above 1 in 10,000, the level at which NASA moves the ISS.
Launched with
Shiyong Tongbu Tongxin Wx. shares its launch, 1986-010, with 4 other bodies the catalogue lists in orbit.
Read from the international designators of the US catalogue: the year and the launch number every piece of one launch shares. A body that has come down is no longer listed.
