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 Portsmouth when that happens.

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.
