In view from you

Nobody watches Sentinel-1A 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.

Even at its closest, Sentinel-1A is too faint to see with the naked eye from anywhere on Earth, so no city page carries pass times for it.

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-1A, 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 Russia LIVE

Where is Sentinel-1A?

At 8:07:03 PM UTC Sentinel-1A was over Russia (57.6° N, 161.4° E), 703 km up, moving at 7.51 km/s and in sunlight.

What is Sentinel-1A?

A satellite that watches the Earth in low Earth orbit, in space since Apr 3, 2014; its mission ended on Jun 29, 2026.

Can I see Sentinel-1A?

No, not with the naked eye: even at its closest, Sentinel-1A is too faint to see from anywhere on Earth; what people use is its pictures and measurements of the Earth.
