0xstarcat / moshier-ephemeris-js Goto Github PK

I noticed the Eclipses are mentioned among the Future work. It would be great to have this feature as eclipses, both lunar and solar have significant impact in astrology.

Starcat.

I noticed you based this library from one library from mivion which is exclusively the moshiers ephemeris, but he has another which is the swiss ephemeris binding in nodejs.

https://github.com/mivion/swisseph

I wonder if this would be a better choice, since by default it uses the moshiers ephemeris, but then you can supply the swiss ephemeris files as well (using their free or professional licence), and gain the extra precision.

This library is not in npm?

Is it possible to add bodies which are not included by default?

For instance, 'Ceres'.

I presume you are using the Swiss ephemeris, in which case, is it possible to add custom objects defined by the body code?

Bodies to add

1. Ceres 0xStarcat/CircularNatalHoroscopeJS#8
2. Juno 0xStarcat/CircularNatalHoroscopeJS#17

How do you calculate the eclipses?
For the Lunar, it comes down to finding how close the moon is to either of the nodes.

Ephemeris.moon.orbit .meanAscendingNode.apparentLongitude
Ephemeris.moon.orbit .meanDescendingNode.apparentLongitude

and comparing it to

Ephemeris.moon.position.apparentGeocentric.longitude
