In view from you
Nobody watches Koronas-Foton 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 Koronas-Foton, 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 far too faint for the naked eye, and catching it would take a telescope driven to follow a point crossing the sky in minutes. What is worth looking at is what it sends back.

Summary
Over the Bay of Bengal LIVE
Where is Koronas-Foton?
At 4:40:51 PM UTC Koronas-Foton was over the Bay of Bengal (19.6° N, 85.8° E), 417 km up, moving at 7.67 km/s and in the Earth’s shadow.
What is Koronas-Foton?
A space telescope in low Earth orbit, in space since Jan 30, 2009.
Can I see Koronas-Foton?
No, not with the naked eye: no brightness has been published for Koronas-Foton, and nothing here estimates one; what people use is what it sees, which its operator publishes.

No operator publishes an ephemeris for Koronas-Foton, so every position here comes from its orbital elements.
In orbit
- Close approaches
- No close approach to Koronas-Foton 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.
Launched with
Koronas-Foton shares its launch, 2009-003, with one other body the catalogue lists in orbit.
| Body | What it is |
|---|---|
| SL-14 R/B | Rocket body |
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.
