Low Flying Moon

This is a bit outdated at this point, but still interesting, I think. On 9/29, the moon was at its lowest point in the sky (during transit) for the past 18 years or so. (Transit is the highest point in the sky over the course of a night, roughly speaking.)

Seems the moon moves between high and low points over the course of a lunar cycle (roughly 4 weeks), but those high and low points get wider and narrower over an 18.6 year cycle, and we just passed the maximum of it. In 9 years, there won't be much difference between the high and low points at all.

Anyway, the long version of this can be found on Wikipedia's article on lunar standstill.
