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. (c) See under Element. -- Magnetic equator, the line around the equatorial parts of the earth at which there is no dip, the dipping needle being horizontal. -- Magnetic field, or Field of…
MAGNETOMETER n.
y, an instrument for determining any of the terrestrial magnetic elements, as the dip and declination.
MICROMETER n.
the object glass of a telescope, and used to determine differences of right ascension and declination between stars by observations of the times at which the stars cross the inner or outer periphery of the ring. -- Double image micrometer, a micrometer in which two images of an object are formed in the field, usually…

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. Place of arms (Mil.), a place calculated for the rendezvous of men in arms, etc., as a fort which affords a safe retreat for hospitals, magazines, etc. Wilhelm. -- High place (Script…
POSITION n.
(as that joining two stars) makes with another fixed line, specifically with a circle of declination. -- Double position (Arith.), the method of solving problems by proceeding with each of two assumed numbers, according to the conditions of the problem, and by comparing the difference of the results with those of the…
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…
RENUNCIATION n.
Formal declination to take out letters of administration, or to assume an office, privilege, or right.
SECTOR n.
imb of which embraces a small portion only of a circle, used for measuring differences of declination too great for the compass of a micrometer.
