    Re: 2020 Nautical Almanac Altitude corrections for moon.

    That's because in the AA there is no complicated "moon correction table" (or "sun correction table) like the one found in the NA. All the corrections are applied separately, which is good for teaching, the student can see where they come from. The only correction that is unique for the moon is the "P in A" and that corrrection is on each page for the moon which is based on the moon's H.P. on that day. So, in correcting a "marine" sextant observations: I.C.; dip, refraction ( for all such observations) then SD for the sun and moon (the SD is found on each daily page),  and then P in A for moon observations. If you want to teach your student how to use the corrections in the NA (why would you?) then print out only those pages and give the students those pages as handouts.
