Three-hour solar eclipse in Thessaloniki




The first solar eclipse of the new year will be visible from Thessaloniki. Only of course for three hours.Fans of this phenomenon should tomorrow be equipped with the necessary specific protective and enjoy the sun even partially hidden.


The sky will not, however dark, as is the total eclipse, or will be particularly fascinating spectacle.However, if the weather allows, ie if there are no clouds, the Thessalonians can see the maximum of the eclipse from the city, which will be at 62.20%.Specifically Thessaloniki eclipse will begin tomorrow at 08:59 when the Sun is 9.5 degrees above the horizon. The maximum is at 10:25, with a height of 20 degrees sun, the eclipse magnitude and rate of 0.7085 solar disk coverage of 62.20%. The eclipse ends with fourth contact at 11:59 and Sun at an altitude of 26 degrees.
 
As the Friends of Astronomy (OFA), the first solar eclipse of the year will be visible almost throughout Europe, North Africa and Central Asia. The penumbra touches the Earth at 8:40 (GMT) in northern Algeria and continues east. The maximum is at 10:50 and the closest point will be the Northern Sweden, where the magnitude of the eclipse is 0.858 (as eclipse magnitude is defined as the percentage of coverage of the diameter of the Sun and the Moon ranges from 0.01 to just over 1). At the time axis of the Moon's shadow passes scratch (just 510 kilometers) from Earth's surface. Unfortunately, nowhere in the globe will have a total eclipse.
 
At present and due to inappropriate hours of the OFA has not planned an event, placing telescopes for viewing the phenomenon from the general public. However, as the president of the OFA Anthony ichi throughout the course of the partial solar eclipse should use proper solar filter, or observing with the naked eye or with binoculars or telescope.

Eclipses in numbers
 
The eclipse is part of the Saro 151 (group eclipses), which began in 1776 and ends in 3056 and includes 72 eclipses, of which twelve are visible from Greece. The last total solar eclipse which was visible from Greece was on March 29, 2006 in Kastelorizo. The next, but need to travel, to enjoy it, it will be in November 2012 and will be visible from Australia.
 
It is estimated by scientists that occur every century on average 238 solar eclipses, of which 84 (35%) are partial, 77 (32%) ring, the eleven (5%) combined annular and total and 66 (28 %) total. In Greece during the 20th century there was only one total solar eclipse on June 19, 1936, and two rings on May 21, 1966 and April 29, 1976. In the 21st century Greece lives two total eclipses. This one took place in 2006 and the second will be held on April 21, 2088 and will be visible in most areas. According to scientists there will be a ring on June 1, 2030. Overall in all regions of the Earth this century will occur 226 solar eclipses, of which 74 will be total, while the same period by 144 lunar eclipses that are total 86.
