Observation of the International Space Station
The International Space Station can easily be spotted with the naked eye. Because of its size (110m x 100m x 30m) it reflects very much sunlight.
The best time to observe the ISS is when it is night time at your location, but the Space Station is sunlit. Such a situation occurs often in the morning before sunrise or in the evening after sunset.
You find a list of the next sighting opportunities for your location below. The green bars indicate the brightness of the ISS on its pass.
