Rated 5 out of 5 stars

Bravo! As someone who observes the Equinoxes, Solstices and Moon Phases as part of my spiritual path, I've been looking EVERYwhere on the web for an open-source, Linux-compatible, browser-based moon-phase tracker, and I found it right here--with solar info to boot! I give the developer four stars just for coming up with the idea and the last (fifth) star for making it available for us Linux-based FireFox users! Bravo, again! :-D
