ISS observation

When can I spot the Space Station?

Observing of the International Space Station

The International Space Station (ISS) can easily be spotted with the naked eye. Because of its size (110m x 100m x 30m), it reflects a large amount of sunlight.

The best time to observe the ISS is when it is nighttime at your location, and the Space Station is sunlit. Often, such a viewing situation occurs in the morning before sunrise, or in the evening after sunset.
