How to see the ISS tonight (without an app)
By Jeroen Wouda · 2 November 2026 · Basics
You do not need an app, a telescope or a dark-sky site to see the International Space Station. You need about ten minutes, a clear horizon and the right ten minutes of the evening. The station is the largest artificial object in orbit, and it reflects sunlight well enough to look like a steady, unusually bright star moving across the sky. The rest is timing.
What you are actually looking at
The station orbits at roughly 400 km, high enough that it is still in sunlight long after the ground below has gone into shadow. That is the whole trick, and it is also why the opportunity is narrow: you need the station lit while your own sky is dark.
What you will see is a point of light, not a shape. It does not blink. It has no red or green navigation lights and no strobe. It moves steadily in one direction, fast enough that you can follow it with your eyes but slow enough that it does not streak. If what you are watching flashes, it is an aircraft.
Why most evenings give you nothing
The station completes an orbit roughly every 92 to 93 minutes — about 15.5 times a day. That sounds like plenty of chances, and it is, for the station. For you, the passes have to line up with dusk or dawn. In full daylight the station is drowned out by the sky; in the middle of the night it is usually inside the Earth's shadow and therefore unlit.
So the workable window is the couple of hours after sunset and the couple of hours before sunrise. Within that window the visible passes come and go quickly. A pass at 21:04 is not followed by another at 21:10; the next one may be an hour and a half later, and by then the geometry may have changed.
Three conditions for a visible pass
A pass is worth going outside for when all three of these hold:
- The station is in sunlight. Usually true near dusk and dawn, often false later at night.
- Your sky is dark enough. The Sun needs to be below the horizon. In midsummer at high latitudes it never gets properly dark, and even a bright pass can be lost in the glow.
- The pass is high enough to clear your surroundings. A pass peaking at 12° above the horizon is invisible behind a house, a hedge or a line of trees.
If one of the three fails, there is nothing to see, and no amount of staring will help.
Finding it without an app
A pass table gives you three useful things: the time of maximum height, the direction the station appears from, and the direction it disappears towards.
Face the entry direction a few minutes early rather than at the stated time — the numbers are a schedule, not a starting gun. Then scan a wide patch of sky instead of fixing on one point. Human eyes are better at catching movement off to the side of where you are looking than at picking out a stationary dot, so sweep slowly and let the movement find you.
If you have a compass, use it once to work out which way north is, then turn from there. Most people are surprisingly bad at guessing direction in an unfamiliar garden at night, and being a quarter-turn out is the most common reason a pass is missed.
What the pass looks like, minute by minute
The station almost always appears low and faint, brightens as it climbs away from the horizon haze, and reaches its best around the time of maximum elevation. Then one of two things happens.
It either sinks towards the opposite horizon and fades out gradually, or it goes dark abruptly, mid-sky, in a clear night. That second ending surprises everyone the first time. Nothing has failed: the station has simply crossed into the Earth's shadow, and a light that was in full sun is suddenly in night. It can happen while the station is still high overhead.
Mistakes worth avoiding
- Being ten minutes late. Passes are short, and the best part is the middle.
- Looking in the wrong direction. The station does not follow a fixed west-to-east path across your sky. Read the azimuths.
- Expecting a disc. At 400 km, even a large object is a point of light to the naked eye.
- Reaching for binoculars. They narrow your field of view and make a moving point harder to find, not easier. The naked eye is the right instrument.
- Standing under trees. A pass at 20° is easily lost behind a roofline.
Where to go next
- Check tonight's timings for your city on the ISS pass pages.
- Learn what the numbers mean in reading a pass table: elevation and azimuth.
- If the table is empty, find out why in why there are no ISS passes this week.
