To expand, I would like a formula/algorithm for calculating the point of intersection of the ecliptic with the local horizon for any given date or place, preferably in units of ecliptic longitude (lambda). Does a relatively straightforward algorithm exist for this problem? I have programming skills and a library of basic astronomical procedures for conversion between the various coordinate systems in use.
