In view from you
Nobody watches DSCS III B-6 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 DSCS III B-6, 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 DSCS III B-6?
At 6:21:30 PM UTC DSCS III B-6 was over the Democratic Republic of the Congo (9.2° S, 24.7° E), 35,785 km up, moving at 3.08 km/s and in sunlight.
What is DSCS III B-6?
A communications satellite in an inclined geosynchronous orbit, in space since Aug 29, 2003.
Can I see DSCS III B-6?
No, not with the naked eye: no brightness has been published for DSCS III B-6, and nothing here estimates one; the dishes and receivers on the ground use its signals instead.

No operator publishes an ephemeris for DSCS III B-6, so every position here comes from its orbital elements.
In orbit
- Close approaches
- No close approach to DSCS III B-6 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
DSCS III B-6 shares its launch, 2003-040, with 2 other bodies the catalogue lists in orbit.
| Body | What it is |
|---|---|
| DELTA 4 R/B | Rocket body |
| IABS 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.
