March and September Equinoxes: the Equator (zero latitude)
June Solstice: Tropic of Cancer, 23.5 degrees north latitude
December Solstice: Tropic of Capricorn, 23.5 degrees south latitude
Not always. The sun is directly overhead at the equator at the spring and fall equinoxes.
The sun is directly overhead at the summer solstice at the Tropic of Cancer (23.5oN). This is as the most northernly latitude which has the sun directly overhead at any time of the year. A similar case happen at the winter solstice at the Tropic of Capricorn (23.5oS).
The sun is most directly overhead near the equator, around the Tropic of Cancer and the Tropic of Capricorn. This occurs during the two equinoxes in March and September.
The two days of the year when the sun is directly overhead at either 23.5 degrees north or south are known as the summer solstice and the winter solstice.
The term for when the sun is directly overhead at noon at the equator is called the equinoxes. This occurs around March 21st and September 23rd each year.
There is no latitude on earth at which the sun would be directly overhead at noon on the equinox and the solstice.
Twice; both during the sun's summer and winter solstices.
If Earth's axis were tilted 45 degrees, the sun would be directly overhead at latitudes of 45 degrees north on the summer solstice, 45 degrees south on the winter solstice, and would pass through the equator on both equinoxes.
Not always. The sun is directly overhead at the equator at the spring and fall equinoxes.
At the Tropic of Capricorn.
No, a person living in New York State cannot see the sun directly overhead at 90 degrees. This is because New York is located at a latitude of about 40.7 degrees North, and the sun is only directly overhead at the equator (0 degrees latitude) during the equinoxes. The sun can be at its highest point in the sky during summer, but it will still be at an angle rather than directly overhead.
The sun is directly overhead at the summer solstice at the Tropic of Cancer (23.5oN). This is as the most northernly latitude which has the sun directly overhead at any time of the year. A similar case happen at the winter solstice at the Tropic of Capricorn (23.5oS).
If you are at the equator, the SUN will be directly overhead during the equinoxes - around 21 March, and 23 September.
The sun is directly overhead in Honolulu, Hawaii, twice a year during the equinoxes, around March 20 and September 23. This phenomenon occurs because Honolulu is located at a latitude of approximately 21.3 degrees North, allowing the sun to be directly overhead at solar noon during these times.
In Bhopal, which is located at a latitude of approximately 23.2° N, the overhead sun can be seen at noon around the equinoxes (March and September) when the sun is directly above the Tropic of Cancer. In contrast, Lucknow, situated at a latitude of about 26.9° N, is too far north to experience the overhead sun at any time of the year. The sun's zenith position does not reach latitudes above 23.5° N, meaning it will never be directly overhead in Lucknow.
The sun is most directly overhead near the equator. This happens during the equinoxes where the sun is directly above the equator, resulting in near-vertical rays at noon.
The Tropic of Cancer ... roughly 23.5 degrees north ... is the most northerly latitude where the sun can ever appear directly overhead.
