EQUATORIAL n.
lel to the axis of the earth, and each carrying a graduated circle, the one for measuring declination, and the other right ascension, or the hour angle, so that the telescope may be directed, even in the daytime, to any star or other object whose right ascension and declination are known. The motion in right ascension…
LOW adv.
In a path near the equator, so that the declination is small, or near the horizon, so that the altitude is small; -- said of the heavenly bodies with reference to the diurnal revolution; as, the moon runs low, that is, is comparatively near the horizon when on or near the meridian.
MAGNETIC; MAGNETICAL a.
are capable or becoming magnetic. (b) (Physics) In respect to terrestrial magnetism, the declination, inclination, and intensity.

PLACE n.
tion in the heavens, as of a heavenly body; -- usually defined by its right ascension and declination, or by its latitude and longitude.

REFRACTION n.
raduated circle for the measurement of refraction. -- Refraction of latitude, longitude, declination, right ascension, etc., the change in the apparent latitude, longitude, etc., of a heavenly body, due to the effect of atmospheric refraction. -- Terrestrial refraction, the change in the apparent altitude of a distan…
