Visible ISS passes over São Paulo

The next visible pass over São Paulo starts on Thursday 29 October at 19:35 local time. The station appears in the south-west, climbs to 76° above the horizon and disappears towards the north-east after 10m 53s.

Visible ISS passes over São Paulo in the next seven days

All times are local (America/Sao_Paulo), 24-hour clock. “Direction” is where the station enters and leaves the sky. Only passes where the Sun is at least 6° below the horizon and the station itself is in sunlight are listed — the ones you can actually see.

The best pass of the week is on Thursday 29 October: it starts at 19:35 in the SW, peaks at 76° in the SE around 19:41, and is over by 19:46. That is the one to put a reminder on.

How to watch it from São Paulo

• Go out two minutes early. The station moves fast enough that a late start usually means you catch only the end of the pass.
• Face the direction in the table. On an ascending pass it travels roughly west-southwest to east-northeast; on a descending pass the other way round.
• No equipment needed. A bright pass looks like a steady white dot, brighter than any star, crossing the sky in about 10m 53s without blinking. Binoculars make it bigger but not more interesting.
• Give your eyes a minute. Look away from street lights and phone screens; the station is easy to see even from a city centre, but a dark spot makes the pass unmistakable.
• Watch the colour. Low passes near the horizon can turn orange or red as sunlight filters through the atmosphere — the same effect as a sunset, because that is exactly what you are seeing.

Why the ISS skips São Paulo for weeks at a time

Seeing the station needs two things at once: it has to be above your horizon, and it has to be sunlit while your sky is dark. The station orbits at 51.6° inclination, so from São Paulo (23.6° south) its ground track shifts west every orbit. For a week or two the evening passes line up with the twilight window and you get a run of good sightings; then the geometry drifts and the station is only up there during the day.

São Paulo's latitude puts the station high overhead, but the evening twilight is short.

How these times are calculated

Every number on this page comes from the current CelesTrak two-line element set (TLE), propagated with SGP4 — the same model NASA and most tracking apps use — and converted to your local horizon with a full topocentric correction. The element set used here is from 28 October 2026, 11:12 UTC. A TLE is good for a few days; over a week the predicted times can drift by a minute or so, and a reboost of the station shifts everything by a few seconds. Check the live tracker on the day itself.

Questions

Can I see the ISS from São Paulo tonight?

Yes — the next visible pass is on Thursday 29 October at 19:35 local time.

How bright is it?

On a pass above 40° the station is typically magnitude −3 to −4, comparable to Venus and bright enough to be followed easily from a lit street. A 15° pass near the horizon is dimmer, more like a bright star, and easier to mistake for an aircraft — but aircraft blink and the station does not.

Does it make a sound?

No. At 400 km the station is far above the atmosphere you hear, and it travels faster than sound could carry anything towards you.
