Saturday is a total lunar eclipse (pointed out to me by Sclerotic_Rings as usual).
Man, I just love these things! Notice how Saturday's lunar eclipse is followed in two weeks by a partial solar eclipse. Also note how that happens again later this year (six months later) in August/September. The reason? When the Earth-Moon-Sun are aligned just right for a part of the year (line of nodes, eclipse season), they may cross each others paths for a couple weeks before and after - this means that whenever there's a solar eclipse (at a New Moon), there's a good chance of a lunar one two weeks before or after (at the Full Moon). And if there's one set on a certain date, there's a good chance six months before or after, halfway around the Sun, that it might happen again.
