Answers on the way the sun crown is heated as well as the causes that provoke the reversal of the sun’s magnetic field every 11 years, will be searched by the Greek mission.
The Greeks departed on Sunday, July 4th to go to the Easter Island where they will be able to observe the first complete sun eclipse which takes place after the reversal of the sun’s magnetic field in 2009. This first eclipse is expected with high interest from the scientific community as it will offer new data concerning the condition of the sun’s magnetic field and if and how it influences the temperature of the sun crown or not. However, this temperature has nothing to do with earth’s temperature.
“When the reversal of the sun’s magnetic field takes place, for example when the south pole becomes north, we can see that the intensity of the magnetic field is reduced as well as the temperature of the sun crown” Giannis Siradakis, professor of physics at Aristotle University of Thessaloniki and head of the mission stated.
The observations will give answers to the major inquiry “how is the sun heated?” According to the current theories, this is achived through its magnetic field or through the impact of its elements that create pressure and thus energy transmission.
Aristidis Voulgaris, the amateur astronomer will also participate in the mission. He created an avant-garde telescope to detect at the same time and accurately the ionization condition (electric charge) of various chemical substances in the sun’s atmosphere. In addition, Thanassis Ikonomou, professor at the University of Chicago who has constructed many spatial devices for NASA missions.
The complete sun eclipse in the Easter Island the 11th of July will last only 4 minutes and it won’ t be obvious from Greece. More specifically, less than 5.000 people will be able to see the eclipse.
