Question 1586Navigation General

The correct answer is B) used in the form of LHA Aries. Sidereal time is used by navigators when determining the Local Hour Angle (LHA) of Aries, which is an important component in celestial navigation. The LHA Aries is the angle between the observer's meridian and the vernal equinox, measured westward. This information is necessary for calculating the positions of celestial bodies and determining a vessel's location using celestial navigation techniques. The other answer choices are incorrect because sidereal time is not directly used for calculating moonrise times (A), determining local apparent time (C), or using the equation of time (D), which are all separate concepts in celestial navigation.
