In view from you
Nobody watches Sinah-1 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 Sinah-1, 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 Argentina LIVE
Where is Sinah-1?
At 6:20:00 PM UTC Sinah-1 was over Argentina (29.1° S, 59.5° W), 682 km up, moving at 7.52 km/s and in sunlight.
What is Sinah-1?
A satellite that watches the Earth in low Earth orbit, in space since Oct 27, 2005.
Can I see Sinah-1?
No, not with the naked eye: no brightness has been published for Sinah-1, and nothing here estimates one; what people use is its pictures and measurements of the Earth.

No operator publishes an ephemeris for Sinah-1, so every position here comes from its orbital elements.
In orbit
- Close approaches
- No close approach to Sinah-1 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.
Launched with
Sinah-1 shares its launch, 2005-043, with 7 other bodies the catalogue lists in orbit.
