Spotting the ISS from a balcony or a small garden
By Jeroen Wouda · 2 November 2026 · Observing
Most advice about watching the space station assumes a field, a dark horizon and an evening to spare. In practice, plenty of good sightings happen from a balcony two floors up, a shared courtyard, or a strip of garden the size of a parking space. What you lose in horizon you can usually make up for by choosing better passes.
What you actually need
Not much. A patch of sky roughly overhead, somewhere to stand safely, and a few minutes. Binoculars are optional and often unhelpful. Dark skies help, but a bright pass does not require them.
The one real constraint is obstruction. A balcony facing a single direction can still show a pass that goes near the zenith, because a high pass crosses most of the sky rather than hugging one horizon. A low pass is different: it needs a clear view in the direction it appears, and a roofline, a tree or a neighbouring block will end it before it starts.
Choose passes by elevation, not by promise
Elevation is the most useful number in a pass table. A pass reaching 70 or 80 degrees goes almost overhead and will be visible from nearly any position with a slice of open sky. A pass peaking at 15 degrees stays close to the horizon and will be lost behind buildings for most urban observers.
As a working rule, prefer passes above about 40 degrees when your view is restricted, and accept that anything under 20 degrees is probably a write-off unless you have a clear line in that direction. Duration follows the same pattern: an overhead pass lasts longer and is easier to catch.
Brightness matters as well, but elevation comes first. A faint overhead pass is usually easier to see than a bright one hidden behind a roof.
Finding the direction
Tables give azimuth: 0 degrees is north, 90 east, 180 south, 270 west. If you can fix north once, from a landmark, a map or the position of the setting sun, you can estimate the rest well enough for a first look.
A phone compass will do the job, with caveats. It reads the magnetic field rather than true north, so it carries a local offset, and steel railings, magnetic cases and nearby vehicles can throw it off badly. Treat it as a rough guide and confirm it against something you can see.
Buildings are the most reliable reference you have. Note which corner of the block the pass should appear past, and look there.
The first thirty seconds
Two things surprise first-time watchers. The station often appears part-way up the sky rather than at the horizon, because it emerges from the Earth's shadow while already overhead. And it is easy to miss while scanning for something dramatic: it looks like a star, and the only way to notice it is to watch for movement.
Start looking two or three minutes early. Sweep slowly rather than staring at a single point. Once you have it, the motion is obvious and you will not lose it.
Light, noise and neighbours
A balcony often comes with a security light or a streetlamp within a few metres. Stand so the lamp is behind you or screened by the wall; the difference in what you can see is larger than you would expect. Keep the phone dim. If you use a torch, red is kinder to your eyes and to anyone else's evening.
If your spot is overlooked, a quiet five minutes is usually fine. Avoid leaning over railings, keep chairs and tripods clear of the edge, and stay out of shared paths.
Photographing a pass from a small space
You do not need a telescope. A phone braced against the railing, set to a night mode with an exposure of a few seconds, will record the station as a short line against the stars, which is a fair record of what it looked like. Longer exposures need a proper mount, and the small field of a balcony makes framing harder rather than easier.
A second target is worth knowing about. Tiangong, the Chinese station, follows the same rules, is often visible on the same evening from the same spot, and is small enough in the sky that the technique is identical.
A word on expectations
From a balcony you will see a point of light, not a spacecraft. There is no detail, no silhouette, no sense of what the thing looks like in photographs. What you get instead is the movement, the silence and the fact that it is there at a time you knew in advance. That is the whole experience, and it holds up.
Where to go next
- Start with the ISS passes page and pick a pass above 40 degrees for your own roof.
- Pass tables or an app: which should you use covers how to find the direction without trusting a phone compass too far.
- Light pollution and seeing satellites explains what to do about the streetlamp outside.
