In view from you
Nobody watches INTELSAT III F-8 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 III F-8, 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 Brazil LIVE
Where is INTELSAT III F-8?
At 5:35:53 PM UTC INTELSAT III F-8 was over Brazil (1.4° S, 50.4° W), 34,783 km up, moving at 3.13 km/s and in sunlight.
What is INTELSAT III F-8?
A communications satellite in an inclined geosynchronous orbit, in space since Jul 23, 1970.
Can I see INTELSAT III F-8?
No, not with the naked eye: no brightness has been published for INTELSAT III F-8, and nothing here estimates one; the dishes and receivers on the ground use its signals instead.

No operator publishes an ephemeris for INTELSAT III F-8, so every position here comes from its orbital elements.
In orbit
- Close approaches
- No close approach to INTELSAT III F-8 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.
