Summary     : Docklet that shows lunar ephemeris to fairly high accuracy
Description :
wmMoonClock displays the lunar ephemeris with high accuracy. You can
define your local latitude and longitude to get precise results. And
even better you get a very nice moon icon that matches the current state
of the moon.

In order to get good results, you may have to find your geographical
coordinates, eg. from this site http://www.astro.com/atlas
