A giant flames burst from the Sun on January 19, 2012. Bursts of plasma waves it throws a light trigger beautiful auroras or the northern sky in the region when the particle is reached with the upper atmosphere of Earth. @ http://solutions-rv.blogspot.com
According to observers of outer space, the Sun's eruptions - also known as a coronal mass ejection - occurred around 16:00 GMT on Thursday. The particles of the explosion hurled toward Earth at speeds of about 1,000 kilometers per second.
"When hit, a large geomagnetic storms arise, and when the particle cloud arrived, visible aurora in the high to middle latitudes," said aerospace analyst, quoted from Spaceweather, January 22, 2012.
A number of space telescopes including the Solar Dynamics Observatory (SDO) and Solar Heliospheric Observatory (SOHO) NASA's managed to make photo and video recording the eruption of the Sun.
According to the Space Weather Prediction Center, the Sun's eruptions came from a group of active sun spots called Region 1401. And the eruption this time, not just a tongue of fire that appears. One other hotspot diesel, which is called by Region 1402, also threw flames.
Of scale created by astronomers to determine the strength of the eruption, the flame that came out last Thursday itself categorized as M2-class sun storm, the storm the sun is strong. M-class solar storm itself is a strong storm, but only came out to medium range.
Posisnya were among the flames, the C-class and weaker X-class solar storms that could bring a very strong threat to satellites and astronauts are in orbit the Sun. The eruption of X-class storms can also disrupt and destroy communications infrastructure if it just leads to Earth.
The sun itself now in the middle of the active phase in the cycle 11 yearly. According to NASA, solar storm cycle that is currently happening, called the Solar Cylce 24, is likely to peak in 2013.
