Webhour angle (HA) Symbol: t.The angle measured westward along the celestial equator from an observer's meridian to the hour circle of a celestial body or point. It is usually expressed in hours, minutes, and seconds from 0h to 24h. It is thus measured in the same units but in the opposite direction to right ascension.The angle measured eastward along the … WebDeclination : This marks the height above or below the equatorial plane for celestial objects. Equivalent to the latitude on earth. it is followed by North or South same as latitude. GHA : GHA (Greenwich Hour Angle) indicates the position past the plane of the Greenwich meridian measured in degrees. Equivalent to longitude on earth.
WebIn particular, the Greenwich Hour Angle (GHA) of a star = Greenwich Sidereal Time - RA of the star. Combining these, we find LHA(star) = GHA(star) - longitude west.
