Today, January 4, Russians will see solar eclipse

Sun

The "Astrogalaktika" informs:

The solar eclipse of 2011. Partial solar eclipse of January 4, 2011

Partial solar eclipse of the fourth day of January, 2011 — this is the 14th eclipse of Saros сто fifty-first. The area gets the best line of sight to the polar and middle latitudes of the Northern Hemisphere.

The eclipse in Moscow, Moscow time:

Beginning Middle End maximum phase
10:38 12:04 13:30 0,813
Eclipse reaches maximum at coordinates 64.7 ° North latitude, 20.8 ° East longitude and has no central band of totality. At the time and in the direction of the point of maximum eclipse of the sun (azimuth) is 155 °.

Dynamic world time in the moment of greatest eclipse: 8:51:42, the amendment dynamic time: 67 seconds. The axis of the shadow is near the north pole, do not cross the Earth's surface, the minimum distance from the Earth to the Moon's shadow cone axis is 6778 kilometers. Thus, Gamma eclipse is 1.0627, and the maximum phase reaches 0.8576.

Number of the lunar month: 136 (was 136 synodic months taken as the zero point date 6 January 2000). Partial solar eclipse Partial Eclipse — solar eclipse where the Earth's surface intersects only the lunar penumbra (the cone of shadow and its sequel does not cross the Earth's surface). The axis of the Moon's shadow January 4, 2011 is at a distance of 400 km. from the surface of the Earth.

Point and the point of maximum eclipse, the moment of greatest eclipse — an event characterized by the minimum of the eclipse distance between the center axis of the cone of the Earth and the moon's shadow. The point of greatest eclipse — a place on the Earth's surface, which in the moment of greatest eclipse phase of the eclipse maximum. For a partial solar eclipse, this point always lies on the boundary of the day and night, and the highest phase is visible at zero height of the sun above the horizon.

The amendment makes the most dynamic time error in the calculation of the parameters of eclipses. This amendment describes the fluctuations of the Earth's rotation caused primarily by the tidal influence of the moon. The resulting fluctuations of the time shift, called deltaT, calculated as follows: on the date up to 1950, based on the identification and approximation of data in the available historical sources, since 1950. Now available on a regular reliable measurement values, deltaT for the future is obtained by extrapolation of the measured values to date, taking into account long-term effects of tidal effects.

30.12.10.Rossiyane 4 January will see the first partial solar eclipse of 2011 goda.Esli lucky with the weather, this event will see the residents and visitors of Moscow and St. Petersburg

January 4, Russians will be able to see the first partial solar eclipse of 2011, reported by the Institute of Applied Astronomy of the Russian Academy of Sciences. In 9 hours and 30 minutes of sun appear in truncated form. When partial solar eclipse will be closed 85% of the solar disk.

Partial solar eclipse is called because the disk of the sun is blocked not completely, but partly. The next partial solar eclipse will occur in March 2015, transferred to the "News".

In St. Petersburg, the solar eclipse will begin at 10 hours and 34 minutes. The moon will slowly but surely moving through the western edge of the solar disk and pass through the northern part.

The greatest eclipse will reach in 11 hours 56 minutes. At this point, the sun will not be a full disk, and a narrow sickle. It is able to see every man armed with tinted glass. A partial solar eclipse will end in 13 hours and 20 minutes.

During the Christmas holidays the sun over Russian territory, if ordered, would get up late. January 4th orb rises in 9 hours 54 minutes, so the eclipse will begin after forty minutes after sunrise. And it will end at the time when the sun reaches the greatest height above the horizon.

Russians will find a very impressive celestial show — low hanging over the city's landscape, reddish sun. St Petersburg was even luckier than the rest of the people of Russia. If the weather does not fail, the greatest phase of the eclipse will be seen is in St. Petersburg.
