Detailed Instructions: In this task you will be given an answer to a question. You need to generate a question. The answer given should be a correct answer for the generated question.
Q: Solar noon (informally high noon) is the moment when the Sun contacts the observer's meridian, reaching its highest position above the horizon on that day ('Sun transit time'). This is also the origin of the terms ante meridiem (a.m.) and post meridiem (p.m.), as noted below. The Sun is directly overhead at solar noon at the Equator on the equinoxes, at the Tropic of Cancer (latitude 23 26 13.0' N) on the June solstice and at the Tropic of Capricorn (23 26 13.0' S) on the December solstice. In the Northern Hemisphere, north of the Tropic of Cancer, the Sun is due south of the observer at solar noon; in the Southern Hemisphere, south of the Tropic of Capricorn, it is due north.
A:
where did the term high noon come from
