the equator The sun is directly overhead at noon on the equator on the first day of spring (vernal equinox) and on the first day of fall (autumnal equinox). The sun is directly overhead at noon on the first day of summer at a point 23.5 degrees north of the equator (called the Tropic of Cancer).
Where can the sun be directly overhead?
Having the sun directly overhead can happen only between the Cancer and Capricorn tropics. That is, only the places between 23.5° of latitude north and 23.5° of latitude south. On the Cancer tropic (23.5° latitude north) it will happen once every year, on the day of the northern hemisphere solstice (about June 21st).
Does the sun ever go directly overhead?
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.
Why is the sun overhead at noon?
Solution. When the sun is overhead at noon, sunlight has to travel a shorter distance through the earth's atmosphere to reach us. During this short journey of sunlight through the atmosphere, only a small amount of the blue light is scattered from the white light, keeping most of the white colour intact within it.
