great links for solar/lunar data

I'm about to reveal some of my secrets here, some of my sources where I learn about interesting celestial events before they're a footnote on the 6 o'clock news.

U.S. Naval Observatory, Astromical Applications Department - The Data Services page has all sorts of astronomical calculators, including a Sun and Moon Data generator for any day.

An example of the data generated, for today:
