Hello:
"You can observe a lot by just watching" said the great Yankee catcher Yogi Berra. I've know for decades that along the New England coast the high and low tides occur about 50 minutes later each day. I've also been aware, more or less, that moon rise and moon set change from day to day. I just never realized the rise and set move later about 50 minutes each day. AHA.....says moi.
The above musing was prompted by Figure 16-1, page 89, in John Letcher's book Self Contained Celestial Navigation with H.O. 208. I've studied this figure in the past and never thought about it too much. The figure shows a rising moon with a higher position ,Ho, on successive evenings at the SAME local time. Really?
