The sun is directly overhead at "high-noon" on the equator twice per year, at the two equinoxes. Spring (or Vernal) Equinox is usually March 20, and Fall (or Autumnal) equinox is usually September 22. Except at the equator, the equinoxes are the only dates with equal daylight and dark.
When the summer solstice happens in the Northern Hemisphere, the North Pole is tilted about 23.4° (23°27´) toward the Sun. Because the Sun's rays are shifted northward from the Equator by the same amount, the vertical noon rays are directly overhead at the Tropic of Cancer (23°27´ N).
23.5° northThe sun's rays are directly overhead along the Tropic of Cancer (the latitude line at 23.5° north, passing through Mexico, Saharan Africa, and India) on June 21.
the Tropic of CancerThe summer solstice occurs when the sun is directly over the Tropic of Cancer, which is located at 23.5° latitude North, and runs through Mexico, the Bahamas, Egypt, Saudi Arabia, India, and southern China.
the Tropic of CapricornThe sun's rays are directly overhead along the Tropic of Capricorn (the latitude line at 23.5° south, passing through Brazil, South Africa, and Australia) on December 21. Without the tilt of the earth's axis, we would have no seasons.
Solution: On Earth's equator, the celestial equator passes through the zenith. On March 21, the Sun is crossing the celestial equator, so it should be found at the zenith (90°) at noon.Dec 11, 2021
The Northern HemisphereThe angle of sunlight is greater in the Southern Hemisphere during the winter. During the June solstice, the opposite is true. The Northern Hemisphere receives the maximum intensity of the sun's rays, while the angle of sunlight decreases in the Southern Hemisphere.
June 21The Summer Solstice (on June 21), is the day when the noon sun is highest in the sky and the duration of daylight is the greatest.
On June 21, the summer solstice of the northern hemisphere, the direct rays are striking 23 1/2 N which is given the special name Tropic of Cancer.Dec 11, 2021
The Sun is currently in the constellation of Pisces.
The equinoxes happen in March (about March 21) and September (about September 23). These are the days when the Sun is exactly above the Equator, which makes day and night of equal length.
So, at the end of the day, while solstices and equinoxes are related, they happen at different times of the year. Just remember that solstices are the longest and shortest days of the year, while equinoxes occur when the day and night are equally as long.
