太陽風暴今將「擊中」地球

美國宇航局說：太陽的日冕物質噴射(CME)朝向地球：預計 8月3日到達
Nasa says CME on Sun headed for Earth: Expected Arrival August 3rdPosted by freedomist on 2:26 AM in CME,

On Sunday, NASA's Solar Dynamics Observatory detected a complex magnetic eruption on the sun. The NASA Solar and Heliospheric Observatory (SOHO) also spotted a large coronal mass ejection (CME) The eruption happened around (3:50 am EST), the SDO detected a C3 class solar flare originating from a group of sunspots (called sunspot 1092). The flare itself was not that large, but the filament located about 70,000 miles away erupted at the same time.
A filament is a large, bright feature extending outward from the Sun's surface, often in a loop shape. Filament is anchored to the Sun's surface in the photosphere, and extends outward into the Sun's corona. It is a long magnetic structure rising above the surface of the sun, filled with cool plasma. The flare and filament erupted at the same time, this suggests they are connected by long-range magnetic field lines. Some believe the flare may have accelerated the eruption of the filament. Eventually, a giant magnetic bubble of plasma broke and blasted out into space.

The problem is, the eruption occurred on the side of the sun facing earth which means, the Coronal Mass Ejection is on its way to the planet earth. It's expected arrival is Aug. 3. This is known as a geomagnetic storm, and they have been known to cause electrical power outages and damage communications satellites. They drive shock waves which produce energetic particles that can be damaging to both electronic equipment and astronauts that venture outside the protection of the Earth's magnetic field.
Expect the government and all observatories to be on high alert.They know a CME is coming, they can probably prepare for its arrival. The reason I find this particular story interesting is because the event being discussed continues to happen more frequently, and on a larger scale than prior events of such a magnitude. Is our solar system going through a time of great change? Should we spend more time laying under the stars? We will see how this particular CME effects earth on August 3rd. It will effect the area of earth facing the sun.

太陽風暴今將「擊中」地球
(星島)2010年8月3日 星期二 15:35
美國 太空總署（NASA）的科學家預測，「太陽風暴」產生的帶電粒子流，今日將「擊中」地球。

科學家預測，「太陽風暴」將衝擊地球磁場，同時在地球兩極產生強烈的極光，那將是非常壯觀絢麗的景象。

但科學家警告，如果「太陽風暴」過分劇烈，將會破壞地球衛星，導致全球大範圍的電力和通信系統中斷。

上周末，各國天文科學家目睹了一場劇烈的「太陽耀斑爆發，耀斑下的太陽黑子足有地球大小，這次爆發隨後引發了太陽表面更大範圍內的「太陽風暴」，向上億公里外的地球噴發出大量帶電粒子，形成一股強烈的太陽風。

「太陽耀斑」是太陽色球層的光亮噴發，又叫色球爆發。它是太陽活動中最為劇烈的現象之一，位置在譜斑或光斑附近，且常在黑子群周圍。

通常，「太陽耀斑」、「日珥爆發」、「日冕物質拋射」等劇烈太陽活動被俗稱為「太陽風暴」，科學家形象地稱之為太陽「打噴嚏」。

今年6月，在美國太空總署任職20年的太陽物理學部門主管理查德•費希利(Richard Fisher)說，太陽的磁能每22年會達到高峰，而太陽黑子的數量或耀斑每11年會達到最高值，這兩種情況會在2013年同時發生。

費希利形容，一旦出現超級「太陽風暴」，「對美國而言，可能造成比卡特里娜 颶風嚴重20倍的經濟損失。」

科學家警告，「太陽風暴」發生時會向周圍空間輸出三種影響：電磁輻射 直接影響地球向日面的大氣層和電離層，對短波通訊造成幹擾；「太陽耀斑」爆發噴射出的大量高能粒子，會嚴重危及太空船的船員和儀器的安全；「日冕物質拋射」，則會引起地球強烈的磁場變化，即磁暴，屆時地表電網可能過熱，航空運輸可能中斷，而電子設施、導航裝置和主要的衛星可能失去功能。
