February 2008 Lunar Eclipse
A total lunar eclipse occurred on February 20 and February 21, 2008. It was visible in the eastern evening sky on February 20 for all of North and South America, and on February 21 in the predawn western sky from most of Africa and Europe. Greatest Eclipse occurring on Thursday, February 21, 2008, at 03:26:03 UTC, totality lasting 49 minutes and 45.6 seconds. Occurring 7.1 days after perigee (Perigee on February 14, 2008) and 6.9 days before apogee (Apogee on February 28, 2008), the Moon's apparent diameter was near the average diameter. The total lunar eclipse was the first of the two lunar eclipses in 2008, with the second, the August 16, 2008 event being partial. The next total lunar eclipse occurred on December 21, 2010. The tables below contain detailed predictions and additional information on the Total Lunar Eclipse of 21 February 2008. The Moon's apparent diameter was 26.2 arcseconds larger than the August 16, 2008 partial lunar eclipse. Eclipse season This is t ...

Lunar Eclipse
A lunar eclipse occurs when the Moon moves into the Earth's shadow. Such alignment occurs during an eclipse season, approximately every six months, during the full moon phase, when the Moon's orbital plane is closest to the plane of the Earth's orbit. This can occur only when the Sun, Earth, and Moon are exactly or very closely aligned (in syzygy) with Earth between the other two, which can happen only on the night of a full moon when the Moon is near either lunar node. The type and length of a lunar eclipse depend on the Moon's proximity to the lunar node. When the moon is totally eclipsed by the Earth, it takes on a reddish color that is caused by the planet when it completely blocks direct sunlight from reaching the Moon surface, as only the light reflected from the lunar surface has been refracted by Earth's atmosphere. This light appears reddish due to the Rayleigh scattering of blue light, the same reason sunrise and sunsets are more orange than during the day. Un ...

Saros (astronomy)
The saros () is a period of exactly 223 synodic months, approximately 6585.3211 days, or 18 years, 10, 11, or 12 days (depending on the number of leap years), and 8 hours, that can be used to predict eclipses of the Sun and Moon. One saros period after an eclipse, the Sun, Earth, and Moon return to approximately the same relative geometry, a near straight line, and a nearly identical eclipse will occur, in what is referred to as an eclipse cycle. A sar is one half of a saros. A series of eclipses that are separated by one saros is called a ''saros series''. It corresponds to: *6,585.321347 solar days *18.029 years *223 synodic months *241.999 draconic months *18.999 eclipse years (38 eclipse seasons) *238.992 anomalistic months The 19 eclipse years means that if there is a solar eclipse (or lunar eclipse), then after one saros a new moon will take place at the same node of the orbit of the Moon, and under these circumstances another eclipse can occur.

Regina, Saskatchewan
Regina () is the capital city of the Provinces and territories of Canada, Canadian province of Saskatchewan. The city is the second-largest in the province, after Saskatoon, and is a commercial centre for southern Saskatchewan. As of the 2021 Canadian census, 2021 census, Regina had a List of cities in Saskatchewan, city population of 226,404, and a List of census metropolitan areas and agglomerations in Canada, Metropolitan Area population of 249,217. It is governed by Regina City Council. The city is surrounded by the Rural Municipality of Sherwood No. 159. Regina was History of Northwest Territories capital cities, previously the seat of government of the Northwest Territories, North-West Territories, of which the current provinces of Saskatchewan and Alberta originally formed part, and of the District of Assiniboia. The site was previously called Wascana ("Buffalo Bones" in Cree), but was renamed to Regina (Latin for "Queen") in 1882 in honour of Queen Victoria. This decisio ...

Eastern European Time
Eastern European Time (EET) is one of the names of UTC+02:00 time zone, 2 hours ahead of Coordinated Universal Time. The zone uses daylight saving time, so that it uses UTC+03:00 during the summer. A number of African countries use UTC+02:00 all year long, where it is called Central Africa Time (CAT), although Egypt and Libya also use the term ''Eastern European Time''. The most populous city in the Eastern European Time zone is Cairo, with the most populous EET city in Europe being Athens. Usage The following countries, parts of countries, and territories use Eastern European Time all year round: * Egypt, since 21 April 2015; used EEST ( UTC+02:00; UTC+03:00 with daylight saving time) from 1988–2010 and 16 May–26 September 2014. See also Egypt Standard Time. * Kaliningrad Oblast (Russia), since 26 October 2014; also used EET in years 1945 and 1991–2011. See also Kaliningrad Time. * Libya, since 27 October 2013; switched from Central European Time, which was u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Central European Time
Central European Time (CET) is a standard time which is 1 hour ahead of Coordinated Universal Time (UTC). The time offset from UTC can be written as UTC+01:00. It is used in most parts of Europe and in a few North African countries. CET is also known as Middle European Time (MET, German: MEZ) and by colloquial names such as Amsterdam Time, Berlin Time, Brussels Time, Madrid Time, Paris Time, Rome Time, Warsaw Time or even Romance Standard Time (RST). The 15th meridian east is the central axis for UTC+01:00 in the world system of time zones. As of 2011, all member states of the European Union observe summer time (daylight saving time), from the last Sunday in March to the last Sunday in October. States within the CET area switch to Central European Summer Time (CEST, UTC+02:00) for the summer. In Africa, UTC+01:00 is called West Africa Time (WAT), where it is used by several countries, year round. Algeria, Morocco, and Tunisia also refer to it as ''Central European ...

NASA
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management f ...

Umbra
The umbra, penumbra and antumbra are three distinct parts of a shadow, created by any light source after impinging on an opaque object. Assuming no diffraction, for a collimated beam (such as a point source) of light, only the umbra is cast. These names are most often used for the shadows cast by celestial bodies, though they are sometimes used to describe levels, such as in sunspots. Umbra The umbra (Latin for "shadow") is the innermost and darkest part of a shadow, where the light source is completely blocked by the occluding body. An observer within the umbra experiences a total eclipse. The umbra of a round body occluding a round light source forms a right circular cone. When viewed from the cone's apex, the two bodies appear the same size. The distance from the Moon to the apex of its umbra is roughly equal to that between the Moon and Earth: . Since Earth's diameter is 3.7 times the Moon's, its umbra extends correspondingly farther: roughly . Penumbra The pe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
