Ophiuchus /ɒfiˈjuːkəs/ is a large constellation located around the celestial equator. Its name is from the Greek Ὀφιοῦχος "serpent-bearer", and it is commonly represented as a man grasping the snake that is represented by the constellation Serpens. Ophiuchus was one of the 48 constellations listed by the 2nd-century astronomer Ptolemy, and it remains one of the 88 modern constellations. It was formerly referred to as Serpentarius /sɜːrpənˈtɛəriəs/ and Anguitenens.
Ophiuchus is located between Aquila, Serpens and Hercules, northwest of the center of the Milky Way. The southern part lies between Scorpius to the west and Sagittarius to the east. In the northern hemisphere, it is best visible in summer. It is located opposite Orion in the sky. Ophiuchus is depicted as a man grasping a serpent; the interposition of his body divides the snake constellation Serpens into two parts, Serpens Caput and Serpens Cauda, which are nonetheless counted as one constellation.
Ophiuchus straddles the equator but lies predominately to its south. However, Rasalhague, a fairly conspicuous star in its north, is circumpolar north of 78° north latitude. The constellation extends southward to −30° declination. Segments of the ecliptic that lie within Ophiuchus lie south of −20° declination. A determination of exactly where these stars are visible on Earth would depend on atmospheric refraction, the Novaya Zemlya effect, mountains and clouds.
Ophiuchus (⛎) (/ɒfiˈjuːkəs/) has sometimes been used in sidereal astrology as a thirteenth sign in addition to the twelve signs of the tropical Zodiac, because the eponymous constellation Ophiuchus (Greek: Ὀφιοῦχος "Serpent-bearer") as defined by the 1930 IAU constellation boundaries is situated behind the sun from November 30 to December 18.
The idea appears to have originated in 1970 with Stephen Schmidt's suggestion of a 14-sign zodiac (also including Cetus as a sign). A 13-sign zodiac has been suggested by Walter Berg and by Mark Yazaki in 1995, a suggestion that achieved some popularity in Japan, where Ophiuchus is known as Hebitsukai-Za (へびつかい座?, "The Serpent Bearer") .
In sidereal and tropical astrology (including sun sign astrology) a 12-sign zodiac is used based on dividing the ecliptic into 12 equal parts rather than the IAU constellation boundaries. That is, astrological signs do not correspond to the constellations which are their namesakes, particularly not in the case of the tropical system where the divisions are fixed relative to the equinox, moving relative to the constellations.
Ophiuchus are a folk/roots rock group from Castle Combe, Wiltshire, England, formed in 1986 by twin brothers - guitarist Jon and bassist Simon Cousins, with saxophonist Pat D'Arcy and photographer, graphic designer Martin Tom Sawyer.
A variety of musicians have performed with the band, including drummer Ed Grimshaw (later of the Warm Jets) and the legendary La's co-founder Mike Badger. The main line-up (1987–1989) was: Jon Cousins (lead vocals/guitar/tin whistle) and Pat D'Arcy (saxophones), with Pete Causer (melodeon/flute/bodhrán), Xavier Tutein (bass), and Myke Vince (drums)
The band released the double A-side, "Serpent And The Bearded King"/"Song For Pym" (produced by Climax Blues Band guitarist Pete Haycock) on their own label, Ophiuchvs Recordvs, and an album on Liverpool's Probe Plus label.
Ophiuchus performed their last concert at the Ashton Court Festival in 1991.
In 2010, after a break of nearly 21 years, the original line-up of the band reformed to perform a number of 'Ophiuchus Reunion' concerts - including an appearance at the 40th anniversary of Glastonbury Festival.
