In view from you
Nobody watches Orbcomm C7 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 Orbcomm C7, 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 Atlantic Ocean LIVE
Where is Orbcomm C7?
At 6:19:53 PM UTC Orbcomm C7 was over the Atlantic Ocean (37.2° S, 3.5° W), 770 km up, moving at 7.47 km/s and in sunlight.
What is Orbcomm C7?
A communications satellite in low Earth orbit, in space since Sep 23, 1998.
Can I see Orbcomm C7?
No, not with the naked eye: no brightness has been published for Orbcomm C7, and nothing here estimates one; the dishes and receivers on the ground use its signals instead.

No operator publishes an ephemeris for Orbcomm C7, so every position here comes from its orbital elements.
In orbit
- Close approaches
- No close approach to Orbcomm C7 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.
