Where is International Space Station (ISS)
Where is International Space Station (ISS) : The European Space Agency (ESA) offers live tracking of the ISS’s position on an interactive map (see bottom of article). To find out where and when to observe it, NASA offers a dedicated app (Spot the Station). There are also several very well-designed smartphone apps.

Spot The Station
NASA has launched a small online app that lets you track upcoming International Space Station flybys. Simply select your country and then your city, and Spot The Station will then tell you what time to look up for the observer. Depending on the position of the ISS’s solar panels and weather conditions, it will be more or less visible in the sky.
The Spot the Station app is available on Android and the App Store here
