In view from you
Nobody watches JTSY 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 JTSY, 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.
Timeline
- Launch
Launched, on the day GCAT records. Source
- Close approach
On Monday, Oct 12 at 6:26 AM UTC, a fragment of Fengyun 1C (NORAD 47101) was to pass within 63 m of Object D (NORAD 49318). The chance was about 1 in 1,000.
Summary
Over the Norwegian Sea LIVE
Where is JTSY?
At 4:55:16 PM UTC JTSY was over the Norwegian Sea (64.1° N, 1.6° E), 911 km up, moving at 7.4 km/s and in sunlight.
What is JTSY?
A communications satellite in low Earth orbit, in space since Oct 14, 2021.
Can I see JTSY?
No, not with the naked eye: no brightness has been published for JTSY, and nothing here estimates one; the dishes and receivers on the ground use its signals instead.

No operator publishes an ephemeris for JTSY, so every position here comes from its orbital elements.
In orbit
- Close approaches
- 1 reported. No close approach to JTSY is reported for the next three 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.
Launched with
JTSY shares its launch, 2021-091, with 2 other bodies the catalogue lists in orbit.
Read from the international designators of the US catalogue: the year and the launch number every piece of one launch shares. A body that has come down is no longer listed.
