In view from you

Nobody watches Sentinel-1D 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-1D, 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.

Sentinel-1D, one reading a day from Sep 16, 2026 to Sep 18, 2026. The band runs from the lowest point of the orbit to the highest; the line is the middle of it.

One reading a day, worked out from the elements Space-Track publishes.

Summary

Over the Atlantic Ocean LIVE

Where is Sentinel-1D?

At 8:07:00 PM UTC Sentinel-1D was over the Atlantic Ocean (13.4° N, 33.6° W), 698 km up, moving at 7.51 km/s and in sunlight.

What is Sentinel-1D?

A satellite that watches the Earth in low Earth orbit, in space since Nov 4, 2025.

Can I see Sentinel-1D?

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

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

Close approaches
Close approaches to Sentinel-1D are not available right now. Try again in a few minutes.
Losing to drag
Sentinel-1D is falling about 2 m a day, read from the last 2 days of samples.
