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. Visible passes – 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. The list contains all visible passes of the ISS during the next ten days. Please select a pass to get more details.” [Enter your city location in the search box for accurate tracking of the ISS]
