What if the solar orbit shifts up & down, north & south of the earth's center as it see-saws back and forth, I know this is a hard thing to visualize but we tend to think in two decisional drawings, while the real universe moves in 3D. I don't know if this would work, but I do think a better understanding of the nature of the ecliptic might yeild other posibilities and promising details as well.

The Sun goes around the ecliptic at an uneven rate and I haven't figured out why this should be in a geocenric system. I freely admit that it is easy to explain in a heliocentric scenario. Neville.
