- Southern celestial hemisphere (Wikipedia)
The southern celestial hemisphere, also called the Southern Sky, is the southern half of the celestial sphere; that is, it lies south of the celestial equator. This arbitrary sphere, on which seemingly fixed stars form constellations, appears to rotate westward around a polar axis due to Earth’s rotation.
- Ptolemy (Wikipedia)
Claudius Ptolemy (/ˈtɒləmi/; Greek: Πτολεμαῖος, Ptolemaios; Latin: Claudius Ptolemaeus; c. 100 – c. 170 AD) was a Roman mathematician, astronomer, astrologer, geographer, and music theorist, who wrote about a dozen scientific treatises, three of which were of importance to later Byzantine, Islamic, and Western European science. The first is the astronomical treatise now known as the Almagest, although it was originally entitled the Mathēmatikē Syntaxis or Mathematical Treatise, and later known as The Greatest Treatise. The second is the Geography, which is a thorough discussion on maps and the geographic knowledge of the Greco-Roman world. The third is the astrological treatise in which he attempted to adapt horoscopic astrology to the Aristotelian natural philosophy of his day. This is sometimes known as the Apotelesmatika (lit. “On the Effects”) but more commonly known as the Tetrábiblos, from the Koine Greek meaning “Four Books”, or by its Latin equivalent Quadripartite.
- Lupus is a constellation of the mid-Southern Sky. Its name is Latin for wolf. Lupus was one of the 48 constellations listed by the 2nd-century astronomer Ptolemy, and it remains one of the 88 modern constellations but was long an asterism associated with the just westerly, larger constellation Centaurus.
- Lepus (constellation) (Wikipedia)
Lepus (/ˈliːpəs/, colloquially /ˈlɛpəs/) is a constellation lying just south of the celestial equator. Its name is Latin for hare. It is located below—immediately south—of Orion (the hunter), and is sometimes represented as a hare being chased by Orion or by Orion’s hunting dogs.
- Douglas Creek (Washington) (Wikipedia)
Douglas Creek is a creek in Douglas County, Washington. It rises in Douglas County, flows through Moses Coulee then empties to Wanapum Lake on the Columbia River. The course of the creek through Moses Coulee displays an “outdoor geologic laboratory” exhibiting basalt formations and relics of the Missoula floods of the last ice age. The watershed of Douglas Creek proper covers 132,056 acres (53,441 ha), about 11% of the county, but including McCarteny Creek the entire Moses Coulee drainage is 1,000 square miles (2,600 km2) or a little more than half of the county. The creek’s flow reaches the Columbia River “during storm water runoff events”, otherwise being absorbed into the aquifer.
