The International Space Station is one of the brightest things in the night sky, but you can only see it when your sky is dark and the station, about 400 km up, is still in sunlight. These are the passes over Porto when that happens.
Next visible pass over Porto
Visible for 5m 28s. It looks like a bright star gliding steadily across the sky, without blinking.
The line is the station’s path over the ground: gold where it is in sunlight, dashed where it is in Earth’s shadow. Inside the white circle it is above Porto’s horizon. Drag the map to move it, and the slider to follow the station along.
The map of this pass loads with the latest orbit…
Times are local to Porto. “Highest” is how far above the horizon the station climbs: 90° is straight overhead, and anything above 40° clears most buildings and trees.

With the app
A time and a direction get you outside. In the dark, with the station already moving, the app does the rest.
Go outside two minutes before the start time and face the direction in the “Appears” column. The station shows up exactly on schedule.
A steady white light, brighter than any star, crossing the sky in a few minutes. It does not blink, and it is faster than a plane at altitude.
When the station flies into Earth’s shadow it fades out in a few seconds. The table shows where each pass ends.
