1. A parallax correction is NOT applied to observations of the ? Stars.
2. What sextant correction corrects the apparent altitude to the equivalent reading at the center of the Earth ? Parallax.
3. Astronomical refraction causes a celestial bodv to appear ? Lower than its actual position.
4. The error in a sextant altitude caused by refraction is greatest when the celestial body is ? Rising.
5. The error in the measurement of the altitude of a celestial body, caused by refraction, increases as the ? Altitude of the body decreases.
6. The correction tables in the front of the Nautical Almanac for use with Sun sights do NOT include the effects of ? Mean refraction.
7. The correction tables in the Nautical Almanac for use with Moon sights do NOT include the effects of ? Augmentation
8. An amplitude of the Sun in high latitudes ? Is most accurate when the Sun's center is observed on the visible horizon.
9. When taking an amplitude, the Sun's center should be observed on the visible horizon when ? The Sun is near or at a solstice.
10.The center of a circle of equal altitude, plotted on the surface of the Earth, is the ? Geographical position of the body.
