Power companies prepare as solar storms set to hit Earth
(Reuters) - Three large explosions from the Sun over the past few days have prompted U.S. government scientists to caution users of satellite, telecommunications and electric equipment to prepare for possible disruptions over the next few days.
"The magnetic storm that is soon to develop probably will be in the moderate to strong level," said Joseph Kunches, a space weather scientist at the Space Weather Prediction Center, a division of the U.S. National Oceanic and Atmospheric Administration (NOAA).
He said solar storms this week could affect communications and global positioning system (GPS) satellites and might even produce an aurora visible as far south as Minnesota and Wisconsin.
An aurora, called aurora borealis or the northern lights in northern latitudes, is a natural light display in the sky in the Arctic and Antarctic regions caused by the collision of energetic charged particles with atoms in the high altitude atmosphere.
Major disruptions from solar activity are rare but have had serious impacts in the past.
In 1989, a solar storm took down the power grid in Quebec, Canada, leaving about six million people without power for several hours.
The largest solar storm ever recorded was in 1859 when communications infrastructure was limited to telegraphs.
The 1859 solar storm hit telegraph offices around the world and caused a giant aurora visible as far south as the Caribbean Islands.
Some telegraph operators reported electric shocks. Papers caught fire. And many telegraph systems continued to send and receive signals even after operators disconnected batteries, NOAA said on its website.
A storm of similar magnitude today could cause up to $2 trillion in damage globally, according to a 2008 report by the National Research Council.
"I don't think this week's solar storms will be anywhere near that. This will be a two or three out of five on the NOAA Space Weather Scale," said Kunches.
SOLAR SCALE
The NOAA Space Weather Scale measures the intensity of a solar storm from one being the lowest intensity to five being the highest, similar to scales that measure the severity of hurricanes, tornadoes and earthquakes.
The first of the three solar explosions from the sun this week already passed the Earth on Thursday with little impact, Kunches said, noting, the second was passing the Earth now and "seems to be stronger."
And the third, he said, "We'll have to see what happens over the next few days. It could exacerbate the disturbance in the Earth's magnetic field caused by the second (storm) or do nothing at all."
Power grid managers receive alerts from the Space Weather Prediction Center to tell them to prepare for solar events, which peak about every 12 years, Tom Bogdan, director of the center said.
He said the next peak, called a solar maximum, was expected in 2013.
"We're coming up to the next solar maximum, so we expect to see more of these storms coming from the sun over the next three to five years," Bogdan said.

這次的太陽風暴來勢洶洶，但就如同往常般，這類真正對整個地球最重要的消息，卻不是那麼得被大眾傳媒所重視。不過要了解它會造成什麼樣的傷害前，我們可以先從過去的案例裡看起。
上圖是2011年3月的地磁數據，我們可以很清楚的看到，在3月1日時地磁數據大幅度下降，在3月11日的時候，也有另一次得大幅下降。在這段期間，太陽黑子產生大爆發。
以下引述自中國科學院雲南天文台:
(2011.2.26～2011.3.4): 大耀斑显示太阳活动开始复苏
近日太阳上出现了多群面积超过数个地球的大黑子群，爆发了X级大耀斑和若干M级中级耀斑，在长达一周多的时间中对地球造成持续冲击。这是自太阳进入第24 个11年活动周以来的首次。2008年开始，太阳活动进入了一段近一个世纪以来最低迷的情态（即太阳之“百年低迷”──它很可能就是造成地球近年来极端气 候等频发全球的根本原因），而在新兔年春节刚过不久发生的这次大黑子及其耀斑爆发，显示太阳活动终于结束了这段极其耐人寻味的“百年低迷”，开始有所昂起 了。这个变化似乎比我们原先估计的来得要快。它是否预示着电影《2012》太阳更猛烈爆发的起步号角，我们当拭目以待。
上面是20110309的太陽風暴，引發了x級的耀班。
上面這一段影片，顯示了在20110309這一個禮拜內全世界的地震次數和規模。我們可以很清楚的看到，在這段時間內，全世界的地震，不論規模和次數都有上昇的傾向。但是最特別的就屬於日本的7.2級大地震。但在兩天後，也就是3月11日，太陽風暴襲擊地球的當日，日本卻又發生了更嚴重的9.0大地震。這全世界都親眼目睹整個過程了。雖然是天災，但有很多證據卻顯示這一場災難卻很有可能是人禍，是美帝用了他們的地震武器所引發的。
你可以看到在火山爆發前，中間出現神秘的藍色閃光。
日本仙台在發生7.4大地震的時候，也出現奇異的藍色閃光。這一切都很有可能跟美帝的Harrp地震武器有關。但他們卻利用了太陽大爆發的這個天時地利。創造出了這一個精密策劃的人禍。
就在2011年8月3日，太陽又產生了一次大爆發。中國科學院也在8月6日發布了太陽質子警報。
地磁數據也出現大量異常。
這次得大爆發也在全世界各地產生異常現象。
首先有民眾用攝影機在美國亞利桑那州拍到疑似兩個太陽的影片，但經確認另一端應該是強烈的太陽風暴與地球大氣層摩擦所產生的強烈極光。
