Weather Station BIMS

The Sun

Weather station BIMS is located in the Netherlands. The explanation below is therefore based on that location.
The information about summer and winter obviously applies to the Northern Hemisphere. Where you see the sun rise (and set) is of course entirely dependent on where you are on this globe at that moment. The perception of the place (which direction to look) of rising and setting of the sun is of course different if you are in a different place on this globe.

There is a huge difference between the place of rise (and fall) in summer and winter. You can try that yourself.
Regularly check the position of rise and/or fall, and you will come to the conclusion that there is a big difference between that place in summer and winter.
That difference becomes greater the more you investigate the same in a place more towards the North Pole.
The further north you go, the bigger the difference becomes. At the Arctic Circle, for example in Rovaniemi, Finland, in summer the sun hardly sets and in winter the day becomes very short. As you go further north (tip: do it, it is beautiful there, especially in winter), eventually the sun doesn't rise anymore. It stays night..

Approximately on June 21 (at the beginning of the astronomical summer), the sun rises in the northeast (azimuth 50°) and sets in the northwest (azimuth 310°). Even in the middle of the (short) summer night, the sun is in the north less than 18 degrees below the horizon. The result: it is not completely dark at night between the end of May and the middle of July. And... the further north you go, the lighter it stays....

On December 21 (the start of the astronomical winter) we get a completely different picture like we saw before. The sun rises (very late) in the southeast (azimuth 125°). In the afternoon the sun does not rise more than about 16 degrees above the southern horizon.
And after a relatively short day, the sun disappears at the beginning of the evening on the southwestern horizon
(azimuth 235°)

The azimuth is one of the coordinates of the horizon coordinate system. In this system, an object's position in the sky is indicated by its two coordinates: azimuth and elevation. The azimuth is the horizontal component therein, the compass direction, i.e. the angle to north measured over the east and thus corresponds to the argument used in surveying.
Usually the azimuth is expressed in degrees. The position of a star on the sky is thus indicated by the azimuth: the compass direction, and the altitude: the angle between the star and the horizon. The whole circle is 360°, north=0°, east=90°, south=180°, west=270°
