In view from you
Nobody watches IRS-1C 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 IRS-1C, 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.
Timeline

Launched, on the day GCAT records. Source
- Close approach
On Wednesday, Nov 4 at 6:42 PM UTC, an unidentified object (NORAD 82180) was to pass within 874 m of IRS 1C (NORAD 23751). The chance was about 1 in 9,000.
Summary
Over the Mediterranean Sea LIVE
Where is IRS-1C?
At 5:38:48 PM UTC IRS-1C was over the Mediterranean Sea (35° N, 16.5° E), 817 km up, moving at 7.45 km/s and in sunlight.
What is IRS-1C?
A satellite that watches the Earth in low Earth orbit, in space since Dec 28, 1995.
Can I see IRS-1C?
No, not with the naked eye: no brightness has been published for IRS-1C, and nothing here estimates one; what people use is its pictures and measurements of the Earth.

No operator publishes an ephemeris for IRS-1C, so every position here comes from its orbital elements.
In orbit
- Close approaches
- 1 reported. No close approach to IRS-1C is reported for the next three 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
IRS-1C shares its launch, 1995-072, with 2 other bodies the catalogue lists in orbit.
Read from the international designators of the US catalogue: the year and the launch number every piece of one launch shares. A body that has come down is no longer listed.
