Solar Tsunami May Hit Earth Anytime
Talking about the tsunami, the mind is a big wave in the ocean. Therefore, the tsunami has caused the sun to the earth's restlessness. The sun has been quiet for the past couple of years. Too quiet. Normally, our home star goes through a sort of rising and falling sleep-wake cycle that lasts 11 years, on average. At the so-called solar maximum, magnetic storms roil its outer layers and sunspots dapple its surface; solar flares arc magnificently into space; and clots of charged particles spew outward in bursts of plasma that can reach to and beyond. At the solar minimum - the stage we've been experiencing lately - all of that drops off dramatically.
Solved, The Mystery Of The Evolution Of The Tsunami Sun
The recent solar minimum has been unnaturally calm, though, with literally no sunspots at all for extended periods, and the eerie silence has gone on for about two years - about twice as long as the typical minimum. "People began to get nervous," says solar astronomer Leon Golub, of the , "that the sun would never come out of it."
But on Aug. 1, the sun woke up with a vengeance: there was, in the breathless words of the website SpaceWeather.com, "a C3-class solar flare, a solar tsunami, multiple filaments of magnetism lifting off the stellar surface, large-scale shaking of the solar corona, radio bursts, a and more." The event was captured in spectacular video by NASA's new Solar Dynamics Observatory, launched in February.
As quoted from Techno Gadgets, during the first break occurred when a big tsunami within the scope of the sun's magnetic field has been moving around the sun's atmosphere. This action set up ideal conditions for the eruption of the routine. The explosion will be towards the earth at different speeds. This is an excellent opportunity to see the huge impact of the tsunami waves, and study the evolution of a low blast that occurred.
Some astronomers say the sun is active is marked with a period of 'suspended animation'. The explosion, which is harmless though, could still have enough power to blow up the satellite revolves around the earth. But the mystery was solved by NASA to study the physical reality of the wave motion obtained from the collision. This wave comes from the movement of the sun points that stand out. This movement is not directly a threat to the earth but still important to understand.
Solar tsunami watchers say that the recent solar eruption could be a sign that the sun is rousing from its relative dormancy. The Earth could be hit by a ‘solar tsunami 2010’ anytime now as a bizarrely difficult magnetic eruption on the Sun has flung a large cloud of electrically charged particles towards our planet, scientists have warned.
"There is increasing waves of the earth than what is received in advance and kept hissing out of the center in a circular pattern on the surface of millions of kilometers. Analysts are skeptical about this call may be overshadowing some of the satellite's eyes, but not the actual wave."
Tsunami Sun is like a tsunami shockwave generated from the matter in the sun. In general, the wave of waves on the surface of the sun can destroy the filamentary material. Generated wave is basically a very strong sun. Technically, this is called wave magnetohidrodinamika very fast or 'magnetohydrodynamical wave' (MHD wave). These waves were first discovered in May 1997 by the Solar and Heliospheric Observatory (SOH) and sometimes referred to as Moreton waves. In May 1997, Coronal Mass Ejection (CME) showing the existence of blasting on the surface of the solar active region. SOHO recorded tsunami ripples appear far from the blast site. However, one view is not sufficient to draw conclusions.
Tsunami Facts Behind the Sun
The solar eruption, called a coronal mass ejection, was spotted by NASA's Solar Dynamics Observatory , which captures high-definition views of the sun at a variety of wavelengths. SDO was launched in February and peers deep into the layers of the sun, investigating the mysteries of its inner workings.
As quoted from the Telegraph, August 1, then most of the earth's surface which faces the sun experiencing frequent eruptions called coronal mass ejection. Tsunami Sun is out 10 million tons of gas plasma is very hot and spread out in space in the linkup of millions of miles per hour.
"This is an eruption that lead to earth and quite large in some time," says Leon Golub, a scientist at the Harvard-Smithsonian Center for Astrophysics, who had warned about this tsunami sun.
For the average person, it's the mass ejection that's most immediately relevant. A giant solar burp has sent a cloud of charged particles racing toward Earth. When the particles, which were predicted to arrive on Tuesday night, slam into , the resulting electromagnetic storm is likely to trigger a spectacular show of northern lights across Russia, North America and northern Europe. It could also scramble communications between orbiting satellites and receivers on Earth, but the relatively modest size of the ejection has led experts to consider a major disruption unlikely. Still, says Golub, "we have no way of predicting this with any certainty."
Solar physicists also haven't got a good handle on why the sun sometimes goes quiet for extended periods. The most recent episode happened about a century ago, but back in the 1600's and early 1700's, the sun sank into a dead calm, known as the Maunder Minimum, that lasted for decades. At its lowest ebb, was about 0.1% of normal for some 30 years.
The sun’s activity frequently ebbs and flows on a fairly expected cycle. Normally, a cycle lasts about 11 years, taking about 5.5 years to move from a solar minimum, a period of time when there are few sunspots, to peak at the solar maximum, throughout which sunspot activity is amplified.
Harvard-Smithsonian Center for Astrophysics representative Leon Golub said that this eruption from the Sun is intended for right at earth and is predictable to get in our world early in the day on Wednesday 4th of August 2010. Experts said that the wave of supercharged gas will likely reach the Earth on Tuesday, when it will bang the natural magnetic shield protecting Earth. It is expected to spark spectacular displays of the aurora or northern and southern lights. The last solar maximum happened in 2001. The latest minimum was mainly weak and long lasting.
Solar Storm Coming from Two Explosion
Still unclear communication equipment failure caused by recent solar storms. But the events that lead to spectacular fireworks, more than one explosion.
"Fireworks spectacular generated by the sun," said British expert Dr Lucie Green of the sun from the Mullard Space Science Laboratory in Surrey who watched the fire of the sun is using Japan's Hinode orbiting telescope.
"The incident is a rare event in which not just one, but almost two successive blasts occurred in different places in the sun that leads to the earth."
"The explosion occurred when a large magnetic structures in the atmosphere of the sun loses its stability and no longer able to resist the gravity of the sun. Like a coil spring is suddenly released, where they would explode in space. "
Dr. Lucie adding "it seems the first explosion was so large that they will change the magnetic field through the half the sun's atmosphere and will cause a second explosion.
The explosion can be directly towards the earth but can also with different speeds. It can provide an excellent opportunity to see the main effects of this explosion, like the aurora or northern lights at low altitude. NASA spokesman could not yet asked for a comment.
The sun caused the tsunami Amazing Aurora
The eruption that could happen is relatively small, described as the level of C3 by astronomers. However, several eruptions that can provide far greater damage on earth. Some eruptions are not too big just to give effect to the earth in the form of auroral display, the light rays toward the north and south poles.
Monday's explosion has caused the Aurora amazing in Danish, Norwegian, Greenland, Germany and some northern areas of the United States and Canada. Aurora in the Danish scene is very significant, because it is located at geomagnetic latitudes that support. But in Michigan territory in the southern U.S. even skywatchers in northern U.S mainland are being told they can look toward the north Tuesday and Wednesday evening for rippling “curtains” of green and red light. Aurora borealis appears due to two minor solar storm that occurred on Sunday (eighth) and fired a lot of plasma in the direction of the earth. While a large explosion in the sun can be dangerous because it can destroy satellites, damaging power plants and communications networks worldwide. Usually only the areas near the polar aurora's all I can see the red and green.
When a coronal mass ejection reaches Earth, solar particles stream down our planet's magnetic field lines toward the poles. In the process, the particles collide with atoms of nitrogen and oxygen in the Earth's atmosphere, which then glow, creating an effect similar to miniature neon signs. The interaction of the solar particles with our planet's magnetic field has the potential to create geomagnetic storms, or disturbances in Earth's magnetosphere. And while aurorae are normally visible only at high latitudes, they can light up the sky even at lower latitudes during a geomagnetic storm. The sun's activity usually ebbs and flows on a fairly predictable cycle. Typically, a cycle lasts about 11 years, taking roughly 5.5 years to move from a solar minimum, a period of time when there are few sunspots, to peak at the solar maximum, during which sunspot activity is amplified. The last solar maximum occurred in 2001. The latest minimum was particularly weak and long- lasting. The most recent solar eruption is one of the first signs that the sun is waking up and heading toward another maximum.
