In the Northern Hemisphere, north is to the left. The Sun rises in the east (far arrow), culminates in the south (to the right) while moving to the right, and sets in the west (near arrow). Both rise and set positions are displaced towards the north in midsummer and the south in midwinter. In the Southern Hemisphere, south is to the left. The ...
As viewed from the Northern Hemisphere, the Sun sets to the northwest (or not at all) in the spring and summer, and to the southwest in the autumn and winter; these seasons are reversed for the Southern Hemisphere. The time of actual sunset is defined in astronomy as two minutes before the upper limb of the Sun disappears below the horizon. [1]
Multiple exposure of midnight sun on Lake Ozhogino in Yakutia, Russia Timelapse video of Lapland's midnight sun in Rovaniemi, Finland. Because there are no permanent human settlements south of the Antarctic Circle, apart from research stations, the countries and territories whose populations experience midnight sun are limited to those crossed by the Arctic Circle: Canada (Yukon, Nunavut, and ...
Sunsets are an hour earlier after daylight saving time ended Sunday. Here are sunrise and sunset times for the next 10 days in Kansas City.
Diagram of Earth's seasons as seen from the north. Far left: summer solstice for the Northern Hemisphere. Front right: summer solstice for the Southern Hemisphere. Although the summer solstice is the longest day of the year for that hemisphere, the dates of earliest sunrise and latest sunset vary by a few days. [8]
Polar night is a phenomenon that occurs in the northernmost and southernmost regions of Earth when the Sun remains below the horizon for more than 24 hours. This only occurs inside the polar circles. [1]
Therefore, δ ☉ = +23.44° at the northern summer solstice and δ ☉ = −23.44° at the southern summer solstice. At the moment of each equinox, the center of the Sun appears to pass through the celestial equator, and δ ☉ is 0°. The Sun's declination at any given moment is calculated by:
The solar zenith angle is the zenith angle of the sun, i.e., the angle between the sun’s rays and the vertical direction.It is the complement to the solar altitude or solar elevation, which is the altitude angle or elevation angle between the sun’s rays and a horizontal plane.
