Sun Ready to burst Tongue of Fire Again

In September 1859, the Sun threw one of the most devastating storm ever recorded in history. Solar eruptions that cause conductive and office telegram (telegram), and triggering dramatic sky phenomena in Cuba and Hawaii.

"A similar storm will likely go back there," says Lika Guhathakurta, scientists from NASA's headquarters, as quoted from Space, July 23, 2011.

In fact, modern society is currently very dependent on technology such as grid systems, satellite-based communications, and GPS. Everything is very vulnerable to storm the Sun.

When a storm occurred in 1859 ago, the Sun is currently still in the cycle (Solar activity moving up and down in a period of approximately 11 years). And the cycle can also serve as a reminder that powerful storms may occur. For information, in the year 2011 is the Sun was at a low cycle.

According to researchers, a storm that occurred in 1859 and puzzling telegram messages perplex astronomers in the tropics. However, the outbreak of the same magnitude if the back there will take a much more serious impact.

Dead lights spread around the world can happen for months. The technicians will be overwhelmed replace damaged electrical transformers, for example. Aircraft and ships can not use GPS for navigation. The banking network is broken. This will disrupt the world trading system.

According to research done in 2008 and by the National Academy of Sciences, a giant sun storm would bring greater economic impact than 20 hurricane Katrina damage. As an illustration, Katrina cause economic losses to U.S. $ 80 billion or about Rp690 trillion.

So, what can we do? As a preliminary, researchers are now trying to predict and track storms more accurately Sun. The aim is that when these storms occur, Earth has been more ready.

"We are now able to track the progress of the Sun in three-dimensional storm like a hurricane track that occur on Earth," said Michael Hesse, Chief of the Space Weather Laboratory, NASA.

"This makes us have a sort of warning alarms to protect the grid and other high technology devices when the sun activity is in the middle of an extreme period," he said.

For example, according to Hesse, disable certain transformer installations generating electricity for several hours to prevent death regional light for several weeks. (Umi)
