| Equinox and Solstice times supplied by the U.S. Naval Observatory, Washington DC. Cross Quarter moments are interpolated as the split or bisector in degrees along the ecliptic between Solstices and Equinoxes. Former NASA rocket scientist Rollin Gillespie applied a spatial application in the mid-1980s to determine cross quarters. Kepler's Third Law says a planet's orbital speed accelerates and decelerates in elliptical orbits. Only circular orbits allow constant orbital speed. Southern Hemisphere seasons oppose the seasons observed north of the Equator. |
