2. On the equinoxes, the subsolar point is at the equator, and the circle of illumination runs through -N and *S. Therefore, the far north and south latitudes of the circle of illumina- o away from the subsolar point. On the June solstice, the subsolar point is at the Tropic N and *S, which latitudes does the circle of illumination pass through on the June solstice? On ON tion are of Cancer at , and the circle of illumination passes through February 26 the subsolar point is at 9°S, and the circle of illumination passes through and

Explanation / Answer

2. On the equinoxes, the subsolar point is at the equator, and the circle of illumination runs through 90oN and 90oS. Therefore, the far North and South latitudes of the circle of illumination are 90o away from subsolar point.

On the June solstice, the subsolar point is at the Tropic of Cancer at 23.5oN, and the circle of illumination passes through 66.5oN and 66.5oS.

In this Case, latitude above 66.5oN receives 24 hours of daylight, and latitude above 66.5oS suffers 24 hours darkness.

Which latitudes does the circle of illumination pass through on June solstice ?

Here also the circle of illumination pass through  66.5oN and 66.5oS.

On february 26 the subsolar point is at 9oS, and the circle of illumination pass through 81oN and 81oS.

Thats all

Thank you.
