Satellite watching in Africa

This post is off the economics topic, but if you are in Africa and interested in science, you might like it. There is a website which displays the path of human made satellites across the African night. The site has Nairobi as the reference point for viewing, and shows (from the ISS link) that the International Space Station will be visible for three minutes between 04.22 and 04.25 tonight (20th October) for example. Other satellites are visible at different times, not all at 4 o'clock in the morning! The viewing point can be changed to your location. The satellites move quickly, like a really distant aeroplane.
