In view from you
Nobody watches Ludi Tance 4A 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 Ludi Tance 4A, 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.

What is Ludi Tance 4A?
A satellite that watches the Earth in an inclined geosynchronous orbit, in space since Aug 12, 2023.
Can I see Ludi Tance 4A?
No, not with the naked eye: no brightness has been published for Ludi Tance 4A, and nothing here estimates one; what people use is its pictures and measurements of the Earth.

No operator publishes an ephemeris for Ludi Tance 4A, so every position here comes from its orbital elements.
In orbit
- Close approaches
- No close approach to Ludi Tance 4A 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.
