In view from you
Nobody watches Sentinel-6B 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 Sentinel-6B, 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.
Altitude
One reading a day, worked out from the elements Space-Track publishes.

Summary
Over the Indian Ocean LIVE
Where is Sentinel-6B?
At 3:03:43 AM UTC Sentinel-6B was over the Indian Ocean (47° S, 89.9° E), 1,350 km up, moving at 7.19 km/s and in sunlight.
What is Sentinel-6B?
A satellite that watches the Earth in low Earth orbit, in space since Nov 17, 2025.
Can I see Sentinel-6B?
No, not with the naked eye: no brightness has been published for Sentinel-6B, and nothing here estimates one; what people use is its pictures and measurements of the Earth.

No operator publishes an ephemeris for Sentinel-6B, so every position here comes from its orbital elements.
In orbit
- Close approaches
- No close approach to Sentinel-6B has been reported publicly in the past thirty days.
- Losing to drag
- Sentinel-6B is falling less than a metre a day, read from the last 48 days of samples.
From Space-Track’s public conjunction messages; the latest report was issued Nov 2, 2026, 1:53 PM, 13 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.
