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 ...
The climate of Norway is more temperate than could be expected for such high latitudes. This is mainly due to the North Atlantic Current with its extension, the Norwegian Current , raising the air temperature; [ 1 ] the prevailing southwesterlies bringing mild air onshore; and the general southwest–northeast orientation of the coast, which ...
Sun path, sometimes also called day arc, refers to the daily (sunrise to sunset) and seasonal arc-like path that the Sun appears to follow across the sky as the Earth rotates and orbits the Sun. The Sun's path affects the length of daytime experienced and amount of daylight received along a certain latitude during a given season.
Blue hour usually lasts about 20–96 minutes right after sunset and right before sunrise. Time of year, location, and air quality all have an influence on the exact time of blue hour. [ 7 ] For instance in Egypt (every 21st of June ), when sunset is at 7:59 PM : blue hour occurs from 7:59 PM to 9:35 PM.
Numerous analyses have been conducted to examine the effects of polar night on humans. In Tromsø, Norway, a city located at 69 degrees north, there is a 2 month long polar night, lasting from mid-November to mid-January. An analysis was conducted based on 2015-16 data from a health survey that involved residents of the region over age 40, with ...
On Tuesday, the sun rose in Utqiaġvik, Alaska, for the first time since November—but only for a whopping 48 minutes before it set again. The sun appeared around 1:15 p.m. and disappeared just ...
Calculate the sunset time, which is the solar noon time plus the sunset hour angle in degree divided by 15; Use the sunset time as input to the solar geometry routine to get the solar azimuth angle at sunset. An interesting feature in the figure on the right is apparent hemispheric symmetry in regions where daily sunrise and sunset actually occur.
Daylight saving time was reintroduced for a final time in 1980, and since 1996 Norway has followed the European Union regarding transition dates. [7] As Svalbard experiences midnight sun during summer, it gives daylight saving time no utility, and is only observed in order to make communicating with Norway Proper more convenient. [4]
