# Where is the subsolar point located today?

## Where is the subsolar point located today?

Since the Earth’s axis is tilted 23.5 degrees, then on this particular day, the Sun’s rays are striking the Earth directly at a latitude approximately 23.5 degrees north of the equator (that is, the Sun’s rays are coming in at an angle of 90 degrees here; this is the subsolar point).

What is Subsolar location?

The subsolar point on a planet is the point at which its sun is perceived to be directly overhead (at the zenith); that is, where the sun’s rays strike the planet exactly perpendicular to its surface. It can also mean the point closest to the sun on an astronomical object, even though the sun might not be visible.

### How do I find my azimuth?

Identify an end point on your map. Mark it as point B. Using the edge of your protractor, draw a straight pencil line between points A and B. The line is your azimuth.

Between which two specific lines of latitude can Subsolar points on Earth be found?

The subsolar point is at the Tropic of Cancer in June, and at the Tropic of Capricorn in December. Midway between the solstices are two dates when the sun shines directly on the equator, and we have a situation like our hypothetical one, where the earth’s axis is perpendicular to the ecliptic.

## Why is the subsolar point not always on the equator?

The subsolar point appears at the Equator twice a year (during the equinoxes), and migrates north and south across the tropics during the rest of the year. The solstices mark when the subsolar point reaches its northernmost and southernmost latitudes.

Where is the subsolar point during the June solstice?

Tropic of Cancer
On the June solstice, the subsolar point is at 23.5 degrees north (see the graphic below). The subsolar points at the solstices define the Tropics. The Tropic of Cancer is 23.5 degrees North, and the Tropic of Capricorn is 23.5 degrees South.

### Where is the subsolar point on June 21?

This is the subsolar point, or the point of maximum insolation. On the June solstice, the subsolar point is at 23.5 degrees north (see the graphic below).

Can I find azimuth on Google Maps?

You can find your PV system’s azimuth by looking at Google Maps! Simply type in your address, and make sure that the red-arrow indicating north is pointing directly to the top of your screen, and that you have ‘satellite’ enabled as the map type.

## How do you find the azimuth on Google Maps?

You can use the measure distance tool and the line draw tool to check line of sight between 2 points on Google Earth.

1. Use the ruler tool to measure the distance between the two points.
2. The ruler tool will show you the distance and the azimuth between the two points.
3. Click ‘Save’ on the ruler tool.

When the subsolar point is located at its highest latitude in the Northern Hemisphere it is?

The line of latitude at 23.5° S where the subsolar point is located on the Winter Solstice (and Sun angle is thus 90°) in the Northern Hemisphere.

### Why does the subsolar point move?

After the September equinox, the subsolar point continues to move south as the Southern Hemisphere tilts toward the sun. Around December 21, the subsolar point hits the Tropic of Capricorn (23.5°S).

Why does the subsolar point change?

At any moment there is one spot on the Earth where the sun is directly overhead. This spot, called the subsolar point, moves around the Earth in one solar day, 24 hours, thus the subsolar point moves 15o of longitude for each hour of the day (360o / 24h). Where this subsolar point is located defines our seasons.
