In view from you

Nobody watches WNISAT-1 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 WNISAT-1, 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.

Summary

Over the Weddell Sea LIVE

Where is WNISAT-1?

At 4:55:13 PM UTC WNISAT-1 was over the Weddell Sea (74.5° S, 59.2° W), 782 km up, moving at 7.43 km/s and in sunlight.

What is WNISAT-1?

A satellite that watches the Earth in low Earth orbit, in space since Nov 21, 2013.

Can I see WNISAT-1?

No, not with the naked eye: no brightness has been published for WNISAT-1, and nothing here estimates one; what people use is its pictures and measurements of the Earth.

No operator publishes an ephemeris for WNISAT-1, so every position here comes from its orbital elements.

In orbit

Close approaches
No close approach to WNISAT-1 has been reported publicly in the past thirty days.

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.
