In view from you
Nobody watches SR 7A 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 SR 7A, 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 to see with the naked eye from anywhere on Earth.
Timeline
- Launch
Launched, on the day GCAT records. Source
- Close approach
On Tuesday, Oct 27 at 11:19 PM UTC, a fragment of Yaogan-50 02 (NORAD 100605) was to pass within 152 m of Solrad 7A (NORAD 730). The chance was about 1 in 7,000.

What is SR 7A?
A satellite in low Earth orbit, in space since Jan 11, 1964.
Can I see SR 7A?
No, not with the naked eye: no brightness has been published for SR 7A, and nothing here estimates one.

No operator publishes an ephemeris for SR 7A, so every position here comes from its orbital elements.
In orbit
- Close approaches
- 1 reported. No close approach to SR 7A 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
SR 7A shares its launch, 1964-001, with 4 other bodies the catalogue lists in orbit.
| Body | What it is |
|---|---|
| THOR AGENA D R/B | Rocket body |
| GGSE 1 (GGRS) | Satellite |
| SECOR 1B | Earth-watching satellite |
| GREB | Satellite |
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.
