Google Earth interactive window

The window displays the transit just as if you were in Google Earth. By default, the view center is located over the point of greatest transit.
It uses my Six Millennium Catalog of Mercury or Venus Transits (6MCST) Web tool engine and therefore requires an Internet connection.

Choose Display > Transit in Google Earth…
If you haven’t yet installed the Google Earth plug-in, you’ll have the opportunity to do so (see the installation screen).
