What is the geographic longitude of a body whose GHA is 232°27'?

A 61°52'W
B 127°33'E
C 61°52'E
D 52°27'E
AI Explanation

The correct answer is B) 127°33'E. The geographic longitude of a body is determined by its Greenwich Hour Angle (GHA). The GHA represents the angular distance, measured westward along the celestial equator, from the vernal equinox to the body's celestial meridian. With a GHA of 232°27', the corresponding geographic longitude is 127°33'E. The other options are incorrect because A) 61°52'W is the geographic longitude for a GHA of 127°33', C) 61°52'E is the geographic longitude for a GHA of 128°08', and D) 52°27'E is the geographic longitude for a GHA of 232°27', which is not the given value.
