In view from you

Nobody watches Feng Yun 1B 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 Feng Yun 1B, 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 it is up there for reaches the ground as pictures and measurements, not as a light in the sky.

Timeline

In orbit

Close approaches
1 reported. On Tuesday, Nov 10 at 12:23 PM UTC, a fragment of Meteor 2-17 (NORAD 28990) passes within 93 m of Fengyun 1B (NORAD 20788). The chance of a collision is about 1 in 700.

From Space-Track’s public conjunction messages; the latest report was issued Nov 8, 2026, 1:11 PM, 3 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.
