Boötes, the Herdsman
Boötes is a constellation north of the celestial equator located at approximately Right Ascension 14.5h and Declination of +10 to +50 degrees. This constellation is one of the Ptolemy's original 48 star patterns. Boötes represents a herdsman driving the Great Bear (Ursa Major) around the sky. The brightest star in the constellation is Arcturus and it is 4th brightest in the entire sky and the brightest star in the northern hemisphere of the sky. Arcturus was important to the pre-historic people of the Pacific: they knew it as Hōkūleʻa and they used it to navigate across thousands of miles of open ocean.
Arcturus is easy to identify because of its brilliance and distinctly orange colour. If you're in doubt but know the stars of The Plough (part of Ursa Major) simply follow the curve of stars in the tail of the Plough - Alioth, Mizar and Alkaid - and you'll reach Arcturus.
