In view from you
Nobody watches DMSP 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 DMSP 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 it is up there for reaches the ground as pictures and measurements, not as a light in the sky.

Summary
Over the Indian Ocean LIVE
Where is DMSP F-12?
At 6:20:41 PM UTC DMSP F-12 was over the Indian Ocean (29° S, 40.7° E), 853 km up, moving at 7.42 km/s and in the Earth’s shadow.
What is DMSP F-12?
A satellite that watches the Earth in low Earth orbit, in space since Aug 29, 1994.
Can I see DMSP F-12?
No, not with the naked eye: no brightness has been published for DMSP F-12, and nothing here estimates one; what people use is its pictures and measurements of the Earth.

No operator publishes an ephemeris for DMSP F-12, so every position here comes from its orbital elements.
In orbit
- Close approaches
- No close approach to DMSP 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.
