The angle of altitude for the zenith is always 90 Azimuth is the number of degrees clockwise from due north (usually) to the object’s vertical circle (i.e., a great circle through the object and the zenith). Altitude of celestial equator on meridian = 90 minus the observer's latitude. Azimuth (az.) The zenith angle is similar to the elevation angle but it is measured from the vertical rather than from the horizontal, thus making the zenith angle = 90° - elevation. Since Sirius is North of the Zenith, we subtract the zenith distance from the declination: our latitude = the declination - the zenith distance = -17° - 39° = -56° (South latitude). The term zenith sometimes means the highest point, way, or level reached by a celestial body on its daily apparent path around a given point of observation.
