When you look at a clear night sky, you can see many stars. A stargazer, or an observational astronomer, usually can identify them one by one.
Western astronomers zone the stars into constellations and name the major stars of a constellation from the brightest to the dimmest, using Greek Letters. For example, Vega, the brightest star of the constellation Lyra, is named Alpha Lyrae (α Lyr). The constellations are usually from Greek Mythology Stories, just like the planets we have in our solar system.
Chinese astronomers also have their own systems for zoning stars. The stars are zoned into asterisms or constellations, also know as “officials”. They imagine each star has its own function in the sky, just like the officials, people and objects on earth.
- The Chinese divides zodiac asterisms into (α) Mansions.
- The Chinese divides the Mansions in (β) Symbols, each Symbol represents a Chinese legendary animal.
- The Chinese divides the asterisms near the North Celestial Pole into (γ) Enclosures, each enclosure equivalents to a place of palace or public market on earth.
- Spica, or α Virginis, the brightest star of the constellation Virgo, is equivalent to a star in the Chinese asterism “Horn” (角宿). The number of Spica in the “Horn” asterism is (δ) （角宿(δ)). i.e. δ=3 if Spica is the 3rd star in the asterism “Horn”.
The coordinates of the cache is 22° 21.ABC’N and 114 02.XYZ’E.
A=γ×(δ+δ)
B=α÷β
C=B+δ
X=A×(β/γ)
Y=B-β-γ
Ζ=β+γ
The GZ is near Tsing Lung Tau（青龍頭）, which means the Dragon’s head. If you know Spica, it belongs to the asterism “Horn”, which is the horn of the Dragon.
