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
For an equinox it is at 0°, which is the equator. For a solstice, it depends on which solstice. For the solstice in June, it is 23.5° North, which is the Tropic of Cancer. For the solstice in December it is 23.5° South, which is over the Tropic of Capricorn.
This happens at the spring equinox and at the autumnal equinox.
Not always. The sun is directly overhead at the equator at the spring and fall equinoxes.
The solstices.
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 directly overhead the Tropic of Cancer on the June Solstice, which can either fall on June 20 or 21 each year.
Location of the sun directly overhead is 13.90 degrees north latitude or 13.54 degrees north latitude in nautical miles at 12 pm UTC/GMT April 27 2012
There is no latitude on earth at which the sun would be directly overhead at noon on the equinox and the solstice.
north and south
Twice; both during the sun's summer and winter solstices.
Not always. The sun is directly overhead at the equator at the spring and fall equinoxes.
At the Tropic of Capricorn.
The solstices.
If you are at the equator, the SUN will be directly overhead during the equinoxes - around 21 March, and 23 September.
The Tropic of Cancer ... roughly 23.5 degrees north ... is the most northerly latitude where the sun can ever appear directly overhead.
At the equinoxes - around 21 May, and 23 September.
This is due to the amazon being quite close to the Equator, where the sun is almost directly overhead. It is at the March and September Equinoxes that the sun is directly overhead at noon.
The sun is directly overhead at either one of the Tropics on either the June or December Solstice.
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).
