Solstices – The longest and shortest days of the
year, when the Sun reaches its greatest angular
distance from the equator. The longest day is the
summer solstice (around June 21) and the shortest
day is the winter solstice (around December 22).
These two are reversed in the southern hemisphere.
Solstice Points – The instant when the Sun is at
either the summer or winter solstice.
Equinoxes (Spring and Fall) -- This is the instant
when Sun crosses the celestial equator at either its
ascending node (Spring Equinox, about March 21) or
its descending node (Fall Equinox, September 23). At
the Spring Equinox, the Sun moves north of the
ecliptic plane, while at the fall Equinox, it moves from
north to south.

Fall Equinox (Autumnal Equinox)
Zero Aries – The intersection of the celestial equator
and the ecliptic. This point undergoes a very slow
backward movement.
Colures – There are two, the equinoctial colure and
the solstitial colure. The equinoctial colure is the hour
circle that passes through the vernal and autumnal
equinoctial points (RA 0h and 12 h). The solstitial
colure is the hour circle that passes through the
summer and winter solstices (0° points of the tropical
zodiac signs Cancer and Capricorn at RA 6h and
18h).
