In view from you

Nobody watches DSCS II F-12 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 II F-12, 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 DSCS II F-12?

At 5:36:38 PM UTC DSCS II F-12 was over Brazil (6.7° S, 67.3° W), 36,305 km up, moving at 3.06 km/s and in sunlight.

What is DSCS II F-12?

A communications satellite in an inclined geosynchronous orbit, in space since Dec 14, 1978.

Can I see DSCS II F-12?

No, not with the naked eye: no brightness has been published for DSCS II F-12, and nothing here estimates one; the dishes and receivers on the ground use its signals instead.

No operator publishes an ephemeris for DSCS II F-12, so every position here comes from its orbital elements.

In orbit

Close approaches
No close approach to DSCS II F-12 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.
