【太陽フレア 観測史上最大の爆発】

■Latest Sun Flare Likely Strongest of Modern Era　

連続１０回！太陽に何が起こっているのか？１１月４日起きた観測史上最大級のフレアは太陽に説明不能の異変が起きていることを表しているのかもしれない。

　

"The strongest flares on record, in 1989 and 2001, were rated at X20. This one is at least that powerful, scientists say. But because it saturated the X-ray detector aboard NOAA's GOES satellite that monitors the Sun, a full analysis has not been done.

The satellite was blinded for 11 minutes.

Craig DeForest, a solar physicist at the Southwest Research Institute, said others in his field are discussing the possibility that Tuesday's flare was an X40."
