[漢羅] 太陽面頂 ê 長蛇形太陽絲

這個月初，有記錄表示太陽面頂出現足長 ê 太陽絲。 咱會當 tī 相片中央看著蛇形 ê 太陽絲，就是彼个較光--ê，彎彎曲曲 ê 弧形結構。 這規條是比 太陽 半徑 ê 一半閣較長，差不多有超過 35 萬公里。 太陽絲是 太陽磁場 tī 太陽表面較懸 ê 所在 聚集燒氣體 組成 ê 結構。 所以咱若是 ùi 邊仔看，伊就變做是一个 咧 peh-升 ê 日珥。 咱閣會當 tī 太陽邊界看著一个無仝--ê、較細 ê 日珥。 這張相片 是假色影像，而且是倒反色--ê。 按呢做，毋若會當強調 太陽絲 ê 結構，而且嘛會當看著 敢若是 地毯 材質 ê 太陽 色球層。 倒爿頂懸 ê 光點實際上是 太陽烏子，差不多是 kah 地球平大粒。 一般講來，太陽絲 會當擋幾若點鐘久，落尾伊會崩塌變做高溫 電漿，落轉去太陽。 是講，有當時仔，in 會 爆炸 噴出粒子 到 太陽系，有一寡仔會驅動地球產生 極光。 這張相片 內底 ê 太陽絲是 9 月初出現--ê，而且會 擋 一禮拜久。

[English] A Long Snaking Filament on the Sun

Earlier this month, the Sun exhibited one of the longer filaments on record. Visible as the bright curving streak around the image center, the snaking filament's full extent was estimated to be over half of the Sun's radius -- more than 350,000 kilometers long. A filament is composed of hot gas held aloft by the Sun's magnetic field, so that viewed from the side it would appear as a raised prominence. A different, smaller prominence is simultaneously visible at the Sun's edge. The featured image is in false-color and color-inverted to highlight not only the filament but the Sun's carpet chromosphere. The bright dot on the upper right is actually a dark sunspot about the size of the Earth. Solar filaments typically last from hours to days, eventually collapsing to return hot plasma back to the Sun. Sometimes, though, they explode and expel particles into the Solar System, some of which trigger auroras on Earth. The pictured filament appeared in early September and continued to hold steady for about a week.
