In view from you

Nobody watches NISAR 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 NISAR, 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.

NISAR, 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 NISAR?

At 8:06:30 PM UTC NISAR was over the Atlantic Ocean (17.5° N, 28.6° W), 752 km up, moving at 7.48 km/s and in sunlight.

What is NISAR?

A satellite that watches the Earth in low Earth orbit, in space since Jul 30, 2025.

Can I see NISAR?

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

Losing to drag
NISAR is falling about 1 m a day, read from the last 2 days of samples.
