I was excited to read about a few new features which have been added to Google Earth 7.1
You need to download / update your version of Google Earth to the latest one first.
You will then be able to do several things:
1. Add, or view the SUN - use the SUN icon on the top toolbar, or go to VIEW and tick SUN
