Code review comment for lp:~stellarium/stellarium/meridian-of-opposition

Yes, the intersecting point is the opposition point. If you mark a longitudinal arc in ecliptical coordinates, let's call this longitude, not meridian. So I propose "opposition longitude" or "oppositional longitude".

OK, building complete. I am afraid this should be split into two semi-circles:

opposition longitude
conjunction longitude (the sun is here!)

Else this is a nice, very welcome addition!
