In view from you

Nobody watches Vela II-A 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 Vela II-A, 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.

In orbit

Close approaches
No close approach to Vela II-A 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.

See every close approach reported in orbit.

Launched with

Vela II-A shares its launch, 1964-040, with one other body the catalogue lists in orbit.
