In view from you

Nobody watches Semi-1N 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 Semi-1N, 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 Gulf of Mexico LIVE

Where is Semi-1N?

At 4:57:00 PM UTC Semi-1N was over the Gulf of Mexico (23° N, 84.7° W), 493 km up, moving at 7.63 km/s and in sunlight.

What is Semi-1N?

A communications satellite in low Earth orbit, in space since Nov 2, 2025.

Can I see Semi-1N?

No, not with the naked eye: no brightness has been published for Semi-1N, and nothing here estimates one; the dishes and receivers on the ground use its signals instead.

No operator publishes an ephemeris for Semi-1N, so every position here comes from its orbital elements.

In orbit

Close approaches
No close approach to Semi-1N 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.
