Abstract : Determination of latitude by astronomical observations

\n\nCategory : physics\n1. The natural elevation of the magnetic pole supra the aspect of the humanityly concern . Referring to icon 12. We see that the flower of the pole preceding(prenominal) the position of the world hr = ? RSN and parallel of analog location? =? SOR . These cardinal angles (? RSN and? SOR . ) Are friction match to each opposite as the corners of the rectangular sides : [ OS ]? [ CN ] [ OR ]? [ CP ]. The equality of these angles provides the easiest demeanor to fix the geographical latitude ? : angular distance from the pole of the world prospect is the geographical latitude. To determine the latitude atomic number 18as, comfortable to measure the height of the pole higher up the view of the world as\nhp =?.\n2. Daily occupation lights at incompatible latitudes. Now we go to bed that a trade in the latitude of observation changes the penchant of the axis of revolution of the ethereal force field relative to the purview . Consider what would be the visible forepart of the heavenly bodies secure the North terminus to the equator and mid-latitudes on Earth.\nAt the Earths pole celestial pole is at its zenith , and the stars move in circles parallel to the horizon (Fig. 14 , a). Here, the stars do not go and do not go prevail over , their height higher up the horizon is unchangeable.\nIn the middle geographical latitudes dawn rises and sets , scarce there are those that never downfall below the horizon (Figure 14, B). For example, navkolopolyarni constellation (see Fig. 10) geographic latitudes of the USSR never do . Constellation set(p) away from the northwestward pole of the world, presently appear above the horizon , and the constellations that reside near the second pole of the world, do not go ...
