The SunTracker The SunTracker is a program that lets you see where the Sun is in the sky at any time of day, anywhere in the world. Just click on a date, choose a place and click on the pink button. If you want to see the movement slower just change the speed. For example, you might want to see what the North Pole in January looks like (very dark). Or you could see Liverpool, Britain and Sydney, Australia on the same day to compare how much sunlight we all receive
