While humanity has been skywatching since ancient times, much of our cosmic understanding has come about only recently. Very recently.

Help with more accurate rising setting and transit calculation for moon (lemmy.world)

I have been working on a hobby program that calculates the times of moonrise and moonset froma given location. for the formulas i have been using Jean Meeus' Astronomical Algorithms book. So far I have successful been able to calculate the ascension and declination for any given date. Currently I am working on the rising setting and transit (chapter 15). My functions work with his example of Venus, but trying with the moon I do not get accurate results. Using the interpolation method in the book does not seem to add accuracy. Am I missing something? Are there specific considerations for the moon that are not included in the book? I would greatly appreciate any advice given!
