Coma Berenices (The Berenice's Hair) Constellation

Altitude: 18.4°   Azimuth: 284.0°   Direction: West-North-West

Coma Berenices (pronounced ˈkoʊmə bɛrəˈnaɪsiːz) is the Latin name of a constellation situated close to the celestial equator. As such, it is at least partly visible from both hemispheres in certain times of the year.

In English language this constellation is also known as "The Berenice's hair" while in astronomical texts and literature this constellation is often abbreviated as "Com" (according to the standard of the International Astronomical Union - IAU) or as "Coma" (according to a naming convention used by NASA).

The Latin genitive of the constellation name is "Comae Berenices" (pronounced ˈkoʊmiː bɛrəˈnaɪsiːz) and it is used to identify some of the brightest stars in this constellation based on the Bayer or Flamsteed star naming convention. For instance: α Comae Berenices (the brightest star of Coma Berenices based on the Bayer catalog); or 23 Comae Berenices (the 23th star in the constellation of Coma Berenices based on the Flamsteed catalog).

Coma Berenices is above the horizon from Greenwich, United Kingdom edit_location_alt. Altitude: 18°.
