Corona Borealis (The Northern Crown) Constellation

Altitude: 43.4°   Azimuth: 269.4°   Direction: West

Corona Borealis (pronounced koʊˈroʊnə ˌbɔːriˈælɪs, -ˈeɪlɪs) is the Latin name of a constellation situated north of the celestial equator. As such, it is more easily visible from the northern hemisphere.

In English language this constellation is also known as "The Northern crown" while in astronomical texts and literature this constellation is often abbreviated as "CrB" (according to the standard of the International Astronomical Union - IAU) or as "CorB" (according to a naming convention used by NASA).

The Latin genitive of the constellation name is "Coronae Borealis" (pronounced koʊˈroʊniː bɔːriˈælɪs) 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 Coronae Borealis (the brightest star of Corona Borealis based on the Bayer catalog); or 23 Coronae Borealis (the 23th star in the constellation of Corona Borealis based on the Flamsteed catalog).

Corona Borealis is above the horizon from Greenwich, United Kingdom edit_location_alt. Altitude: 43°.
