Example text

The declination, d, is measured from the celestial equator along the hour circle through the star. (b) The observer’s view. A south-facing observer sees the right ascension increasing along the celestial equator to the left from the Vernal equinox. This is the (RA, d) version of the equatorial system. F. Milone. (3) The polar angle at the zenith, between the vertical circles through the North point and that through the object celestial equator. The angular distance away from the celestial equator and toward the poles is called declination (from the Latin declinatio or “bending away”) and originally referred to the distance from the celestial equator of a point on the ecliptic, the Sun’s apparent annual path in the sky.

Many later cultures identify the winter solstice as the point of the annual death and rebirth of the Sun. A shaft of sunlight penetrates into the inner chamber of Brugh-na-boinne at winter solstice sunrise, in fitting tribute to such a belief. The best-known megalithic monument is undoubtedly Stonehenge, in southern England. Hawkins (1963, 1965a) has argued that a series of holes associated with the monument was used to predict eclipses, and certainly someone with a modern knowledge of eclipses could have used Stonehenge for such a purpose.

3. The Equatorial or “Chinese” System In ancient China, another system was in use that is similar to the modern equatorial system. The modern equatorial system enables a transient object to be located precisely among the stars at a particular time. 3) is the celestial equator, the sky analog of the Earth’s equator. It is midway between the poles of the equatorial system, the north and south celestial poles, the sky analogs of the North and South Poles of Earth. 2. The Sphere of the Sky moment by moment, at a given point in the sky, other than exactly at a pole.
