In view from you
Nobody watches Coriolis 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 Coriolis, 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 Tasman Sea LIVE
Where is Coriolis?
At 6:20:21 PM UTC Coriolis was over the Tasman Sea (49.9° S, 164° E), 842 km up, moving at 7.43 km/s and in sunlight.
What is Coriolis?
A satellite that watches the Earth in low Earth orbit, in space since Jan 6, 2003.
Can I see Coriolis?
No, not with the naked eye: no brightness has been published for Coriolis, and nothing here estimates one; what people use is its pictures and measurements of the Earth.

No operator publishes an ephemeris for Coriolis, so every position here comes from its orbital elements.
In orbit
- Close approaches
- No close approach to Coriolis 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.
