1-49. The correction for parallax, which must be made for precise computa- tions, accounts for the 1. refraction of the rays of the sun 2. gravitational differential created by the direction of the plumb line 3. displacement of the horizon plane 4. elliptical variation of the surface of the earth 1-50. The side of the astronomical triangle between the pole and the star is known as the 1. colatitude 2. coaltitude 3. parallactic 4. codeclination Learning  Objective:  Determine  the celestial coordinate when given meridian  altitude  observation. IN ANSWERING QUESTIONS 1-51 AND 1-52, REFER TO TABLES 15-1 AND 15-2 IN YOUR TEXTBOOK. 1-51. What was the GHA of the sun at zone 1-52 1-53 1-54 time  09h22m14s on 16 May 1986 in longitude   79°37’12"W? 1. 293°51.9´ 2. 97°47.6´ 3. 94°51.2´ 4. 36°28.7´ What was the declination of the sun at the time and place in question 1-51? 1. S   8°59.2’ 2. N 19°07.1’ 3. N 19°07.9’ 4. N 19°08.1’ What is the polar distance, measured from the elevated north pole of the celestial body whose declination is 20°S? 1. 20° 2. 70° 3. 110° 4. 200° In a time diagram, the observer is  located  at  what  point? 1. Over the north celestial pole 2. On the celestial equator 3. On the Greenwich meridian 4. Over the south celestial pole 1-55. The GHA of a star is measured in what  manner? 1. Counterclockwise from Greenwich to the star only 2. Clockwise from Greenwich to the star only 3. The same direction from Greenwich to the star 4. The same direction from the star to Greenwich 1-56. LHA is always measured from the local meridian in what direction? 1. Northward 2. Southward 3. Eastward 4. Westward 1-57. What method is used to obtain the 1-58 1-59 LHA when the GHA and longitude are known? 1. Always add the longitude to the  GHA 2. Always subtract the longitude from the GHA 3. Subtract an eastern longitude from the GHA and add a western longitude to the GHA 4. Add an eastern longitude to the GHA and subtract a western longitude from the GHA What is the polar distance of a heavenly  body? 1. The declination at that instant 2. 90° minus the declination 3. 180° minus the declination 4. 270° minus the declination The difference between the surface- plane altitude value and the center-of-the-earth-plane  altitude value is what type of correction? 1. Semidiameter 2. Refraction 3. Parallax 4. Upper limb Learning   Objective:   Identify methods, procedures, and calculations required to determine latitude  and  azimuth. 5
