For a high enough latitude, the upper and lower passages of the sun and moon will be observable
The lower right hand corner of a Nautical Almanac right hand page has both upper and lower meridian passage for the moon. Why the lower?
In reply to a similar question in Sep 2013 Herbert Prinz made reference to circumpolar stars. I get that, as you might be able to observe both transits. But why for the moon?
