Partial solar eclipse VISIBLE ON JANUARY 4

FROM 09:00 TO START THE PHENOMENON, BUT IN GREECE WE SEE ONLY TWO THIRDS OF THE SOLAR DISK TO BE COVERED BY THE MOON AND IT WILL HAPPEN AT THE MAXIMUM PHASE OF ECLIPSE, 10:23 A.M.

Provided, of course, there are no clouds! If weather conditions permit the entrance of the Digital Planetarium of the Eugenides Foundation (Pentelis 11, P. Faliro), telescopes will be installed the Greek Astronomical Union, and amateur astronomers will help stakeholders to see the partial eclipse of the Sun through the telescope. Almost 12 hours earlier, the Earth is at perihelion, ie the closest distance from the Sun (km 147 105 721). The eclipse will begin at 8:40 a.m. Northern Algeria and will be visible from North Africa, most of Europe and Central Asia. Solar eclipses occur when the Moon passes in front of the disk of the sun and covering either partially or totally with the shade leaves on the our planet. The shadow consists of two distinct regions: an inner cone of complete shadow called a shadow and a main area of partial shadow called the penumbra. When observing an eclipse of the Sun from an area of land on which falls the penumbra, the Moon covers only part the Sun and then it is a partial eclipse of the Sun. When we look at the Sun from an area covering the full shadow of the Moon, the Sun is completely invisible and then the sun eclipse is total. The largest number of lunar and solar eclipses can be observed during one year is seven and the youngest two (when the two will certainly be solar). The largest number of lunar eclipses in a calendar year shall not exceed three, while the maximum number of solar eclipses can reach five. estimated to occur every century on average 238 solar eclipses, of which 84 (35%) are partial, 77 (32%) is annular, the 11 (5%) is annular and total gross and 66 (28%) is total. From 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 in Greece will be two total eclipses (on March 29, 2006 only visible in Kastelorizo ​​and April 21, 2088 in most areas) and a ring (on June 1, 2030). total in all regions of the Earth the 21st century will occur 226 solar eclipses, of which 74 will be (for at least part of their length) total, while the same period, from 144 lunar eclipses, the total is 86.
