NASA's Solar Dynamics Observatory spotted the summer's first 'X' solar flare on Friday - a huge outburst from the sun right at the top of the scale.
NASA 的太陽動態觀測衛星6日觀察到今夏第一個X級太陽閃焰,也就是巨大太陽噴發,威力為閃焰分類最高級
This came on the back of 12 'M' flares in just six days, with a M6.1 flare knocking out radio signals across the planet on Thursday - hinting at the destruction the sun could reign on our technology if Earth takes a full blast across its blow.
The sunspot group behind the flares - named as AR1515 - stretches across 118,681 miles (191,000km) of the sun's surface.
產生這些太陽閃焰的太陽黑子群編號為AR1515,綿延在19萬1000公里的太陽表面上
This makes it's width more than 15 Earths set end to end, said NASA solar astrophysicist C. Alex Young.
美國太空總署太陽天體物理學家楊恩(C. Alex Young)說,這些太陽黑子的寬度,超過15個地球連結起來的長度
The biggest flares are known as 'X-class flares' based on a classification system that divides solar flares according to their strength.
根據依照太陽閃焰威力制定出來的分類系統,最大的太陽閃焰稱為「X級閃焰」
The smallest ones are A-class, which are similar to normal background levels, followed by B, C, M and X.
最小的太陽閃焰為A級,接著依序是B、C、M與X級
Similar to the Richter scale for earthquakes, each letter represents a 10-fold increase in energy output, meaning an X is ten times an M and 100 times a C.
閃焰分類系統類似地震的芮氏規模,每個字母代表能量輸出增加10倍,意味X是M的10倍,C的100倍
The sun is now heading into the peak of its 11-year solar flare cycle, with 2013 expected to the tumultuous year.
太陽正邁向11年太陽閃焰週期的高峰,2013年將會是威力最強的一年
With the increased spread in communications in the last 11 years, a sever solar storm could cause huge issues for the planet.
