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 Sun rises in the east (near arrow), culminates in ...
[8] [9] The figure on the right is calculated using the solar geometry routine as follows: [10] For a given latitude and a given date, calculate the declination of the Sun using longitude and solar noon time as inputs to the routine; Calculate the sunset hour angle using the sunset equation;
The shortest day is two weeks away, but the earliest sunsets are here. The earliest sunset (Dec. 4) and latest sunrise (Jan. 11) are 38 days apart.
The time when the Sun transits the observer's meridian depends on the geographic longitude. To find the Sun's position for a given location at a given time, one may therefore proceed in three steps as follows: [1] [2] calculate the Sun's position in the ecliptic coordinate system, convert to the equatorial coordinate system, and
Midnight sun, also known as polar day, is a natural phenomenon that occurs in the summer months in places north of the Arctic Circle or south of the Antarctic Circle, when the Sun remains visible at the local midnight. When midnight sun is seen in the Arctic, the Sun appears to move from left to right.
It is on the celestial equator at both the left and right extremes of the sky chart, with the ecliptic (the orange dotted sine curve) passing through it. The first point of Aries , also known as the cusp of Aries , is the location of the March equinox (the vernal equinox in the northern hemisphere, and the autumnal equinox in the southern ...
In Toronto, the setting sun lines up with the east–west streets on February 16 and October 25, a phenomenon now known locally as Torontohenge. [23] In Montreal , there is a Montrealhenge each year around June 12.
