Orbital elements: CelesTrak, epoch 2026-09-01 11:57 UTC. Elevation-only predictor (no direction of travel); passes above 10°; darkness = sun below −6° at Los Angeles; shadow check at each pass's peak. All times PDT. Computed 7:51 PM, refreshed every 30 minutes.

How to spot the ISS

Be outside two minutes before the rise time with as much open sky as you can find. City lights are fine — the station outshines them.
Look for a steady, un-blinking star moving about as fast as a high airliner. No flashing lights, no sound. If it blinks, it is a plane.
It is brightest near the “highest” time on the card — that is when it is closest to you. Passes above 60° go almost overhead.
If it fades out mid-sky, that is normal — it just flew into Earth's shadow. Wave anyway; the crew is up there.

Get launch alerts

Night launches from Vandenberg are visible from Los Angeles. One email a day before, an hour before, and at liftoff — no account.

Frequently asked

How bright is the ISS?

On a high pass the International Space Station reaches magnitude −3 to −6 — brighter than any star and comparable to Venus — a steady white point that does not blink and makes no sound. Tiangong is a step dimmer (about −1 to −3) and Hubble is a faint, steady star (+1 to +2) that wants a dark sky. Our brightness hint uses peak elevation only: passes above 60° are the bright ones; below 30° the object stays low in haze.

Why do passes end abruptly?

A satellite is visible only while it is in sunlight and you are in darkness. When it flies into Earth's shadow it fades out over a few seconds — often still high in the sky. That is not cloud: it is orbital sunset. Passes an hour or two after dusk usually end this way; passes before dawn often begin this way, with the station appearing out of nothing overhead.

Why are there no passes over Los Angeles some nights?

The ISS orbits at 51.6° inclination and its ground track drifts west about 22° each orbit, so it overflies Los Angeles in runs of a week or two, then swings away for a similar stretch. Even when it does pass over, the sun angle has to line up so the station is lit while your sky is dark. Tiangong (41.5°) and Hubble (28.5°) never climb high for cities north of those latitudes — Los Angeles is at 34.1°N, so Hubble stays low on the southern horizon here.
