Actually at 23.5 degrees it is never overhead because the Earth's axial tilt is only 23.44 degrees. However, for the purposes of this answer let us round up to 23.5 degrees.
The Tropic of Cancer is located at 23.5° North of the equator.
The Tropic of Capricorn lies at 23.5° South of the equator.
There is one day each year when the Sun is overhead (90 degrees) at these latitudes. In the North this is at the Summer Solstice in June (around the 21st) each year and in the South it is at the Winter Solstice in December (around the 21st) each year.

What is the moment when the sun appears to be across the celestial equator called?
The sun appears to cross the celestial equator twice in the course of one year. The point in the sky where the sun appears to cross the celestial equator on its way south is called the Autumnal Equinox. The moment when it appears to be in that position is called the "Beginning of Fall" in the northern hemisphere. The point in the sky where the sun appears to cross the celestial equator on its way north is called the Vernal Equinox. The moment when it appears to be in that position is called the "Beginning of Spring" in the northern hemisphere.This happens at the equinox, which is around March 21 and September 21. (The date varies a day or so either way, depending on the cycle of leap years.)If you need to know exactly when this is, you can look that up on the US Naval Observatory's web site on the "Earth's Seasons" page (linked below).
The sun is on the celestial equator at the times of the?
The equinoxes are the two points on the celestial equator there the ecliptic(the sun's apparent annual path through the stars) crosses it.Note that the equinoxes are not events or dates. They are points on the mapof the stars.
Where is the sun when there is a equinox and how is the day and night time compare at that time?
The sun is at the celestial equator, appearing to go Northwards at the vernal equinox and southwards at the autumnal equinox. The word equinox derives from the Latin roots for "equal" and "night" and so, not surprisingly, the night time is the same as day time: 12 hours each.
During an equinox the sun is directly over what part of earth?
During an equinox, the sun is directly over the equator of the Earth. This causes the length of day and night to be nearly equal all over the world.
What is a cross staff and astrolabe?
A cross staff is a navigational instrument used for measuring angles or distances at sea. It consists of a perpendicular staff with sliding parts to align with the celestial body being observed. An astrolabe is an ancient astronomical instrument used to determine the time of day or night based on the position of the stars and planets. It could also be used to determine latitude by measuring the altitude of celestial bodies.
How far from zenith is the celestial equator when it crosses the celestial?
The angle between the celestial equator and your personal zenith is equal to the latitude of your location. (Whether it's north or south latitude doesn't matter, and neither does your longitude or the time of day or night where you are.)
The celestial equator always crosses the horizon at the east point and west point?
This is true. The celestial equator ... the line of zero declination ... crosses the horizon due east and due west. However, the ecliptic ... the apparent path of the sun through the stars ... is inclined to the celestial equator, and can hit the horizon anywhere within 23.5 degrees north or south of the east-west directions, depending on the time of day and day of the year.

What is the difference between equator and equinox?
The Equator is an imaginary line (great circle) on the Earth's surface, which is equidistant from both the geographic poles and lies in a plane perpendicular to the Earth's axis of rotation. It divides the Earth into the Northern and Southern Hemispheres.An Equinox is either of the two times during a year when the sun crosses the celestial equator. At this time, the length of day and night are approximately equal as the Sun is exactly above the Equator.The vernal equinox occurs around March 21, when the Sun moves north across the celestial equator. The autumnal equinox falls around September 23, as the Sun crosses the celestial equator going south.
During an equinox the sun is directly over what part of earth?
During an equinox, the sun is directly over the equator of the Earth. This causes the length of day and night to be nearly equal all over the world.
The celestial coordinates of the autumnal equinox are?
The celestial coordinates of the autumnal equinox are 0 hours right ascension and 0 degrees declination. This marks the point at which the sun crosses the celestial equator, and day and night are of equal length.
What is an equionox?
An equinox is when the sun crosses the celestial equator, resulting in day and night being nearly equal lengths all over the world. There are two equinoxes each year: the vernal equinox in March and the autumnal equinox in September.
Are there two different first days of spring meteorological and or astronomical?
Yes, meteorologists have decided they they regard the first day of March in the northern hemisphere as the first day of spring. In astronomical terms the first day of spring is when the sun crosses the celestial equator which occurs around 20/21st March. In the southern hemisphere spring begins in September. Again on the first of the month or at the equinox when the sun once more crosses the celestial equator.

The Sun crosses the celestial equator going north This is known as the spring?
The Sun crossing the celestial equator going north is known as the vernal equinox or the first day of spring. This event marks the beginning of longer days and shorter nights in the Northern Hemisphere, signifying the start of the spring season. It occurs around March 20th each year.
