Solar / lunar eclipses notation

Open GitAttila opened this issue 3 years ago • 1 comments

Is there a way to find out from the existing generated Horoscope object whether the sun and moon are eclipsed? I checked the Ephemeris.mon.position and could not find any information, nor on the sun object. I was checking particularly for the date of April/20/2022 which is to be a solar eclipse. Is there a way to infer this from the existing data? If not, could the information about solar and/or lunar eclipse be added to the horoscope object?

As far as I can see, for lunar eclipses, it comes down to finding how close the moon is to either of the nodes. I'm not sure on this, but I assume it could be calculated from

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

and comparing it to

Ephemeris.moon.position.apparentGeocentric.longitude
