In view from you
Nobody watches INTELSAT IVA F4 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 INTELSAT IVA F4, 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 reaches you from it reaches a dish or an antenna, not an eye.

Summary
Over the Democratic Republic of the Congo LIVE
Where is INTELSAT IVA F4?
At 5:36:36 PM UTC INTELSAT IVA F4 was over the Democratic Republic of the Congo (3.8° N, 24.3° E), 36,035 km up, moving at 3.07 km/s and in sunlight.
What is INTELSAT IVA F4?
A communications satellite in an inclined geosynchronous orbit, in space since May 26, 1977.
Can I see INTELSAT IVA F4?
No, not with the naked eye: no brightness has been published for INTELSAT IVA F4, and nothing here estimates one; the dishes and receivers on the ground use its signals instead.

No operator publishes an ephemeris for INTELSAT IVA F4, so every position here comes from its orbital elements.
In orbit
- Close approaches
- No close approach to INTELSAT IVA F4 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
INTELSAT IVA F4 shares its launch, 1977-041, with one other body the catalogue lists in orbit.
| Body | What it is |
|---|---|
| ATLAS CENTAUR R/B | Rocket body |
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.
