In view from you
Nobody watches Kosmos-448 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 Kosmos-448, 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 Barents Sea LIVE
Where is Kosmos-448?
At 11:30:14 PM UTC Kosmos-448 was over the Barents Sea (71.6° N, 29.7° E), 1,512 km up, moving at 7.11 km/s and in sunlight.
What is Kosmos-448?
A communications satellite in low Earth orbit, in space since Oct 13, 1971.
Can I see Kosmos-448?
No, not with the naked eye: no brightness has been published for Kosmos-448, and nothing here estimates one; the dishes and receivers on the ground use its signals instead.

No operator publishes an ephemeris for Kosmos-448, so every position here comes from its orbital elements.
In orbit
- Close approaches
- No close approach to Kosmos-448 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.
