@mivion any advice how north and south moon nodes can be calculated?

mivion commented 7 years ago

This library provides calculations only for bodies. To calc nodes of moon see swisseph.

Thanks for the reply. I'm interested in the solution that can be used on JS client-side. Is it possible to implement it in JS? What is needed for this?

May some one helps?

Is this the place where algorithm can be taken from?

@whitecolor fwiw I found the formula for the Mean Ascending Node and Mean Perigee in a book titled Astronomical Algorithims by Jean Meeus and implemented them into my fork of this repo. Here's the commit and the implementation is in src/utilities/luna.js https://github.com/0xStarcat/Moshier-Ephemeris-JS/commit/1d3b02d8024d63f27e8532901a7581a417a282c5
