[漢羅] 太陽西爿邊界 ê 太陽絲爆發

太陽絲 是 tī 太陽表面 ê 太陽活跳區 頂懸，循環磁場發出 ê 超大型、超高溫 ê 電漿流。 Kah 太陽盤比起來，太陽絲看起來烏烏，這是因為伊 ê 溫度較低，所以看起來比 太陽光球層 較暗。 這寡浮 tī 太陽邊界頂懸 ê 結構，若是背景是烏暗 ê 太空，in 看起來就會較光，這个時陣咱就 kā 叫做 日珥。 太陽絲爆發包括 ùi 太陽盤頭前行過--ê，kah 湠到太陽邊界外口 ê 磁化電漿流。 Hα 波段 ê 太陽特寫是 tī 6 月 22 翕--ê。 太陽活跳區 AR3038 就 tī 正爿，欲倚 太陽西爿邊界 遐。 太陽活跳區 AR3038 是綴太陽踅到邊界 ê 時陣才看會著--ê。 過去 tī 太陽活跳區頂懸遮爾大 ê 太陽絲，這馬變做是日珥 ê 一部份。 毋知你敢知影太陽活跳區 AR3038 ê 太陽絲爆發是有偌大？ 相片正爿頂懸角仔遐，有囥一粒地球做比例，予你做參考。

[English] Filaprom on the Western Limb

A solar filament is an enormous stream of incandescent plasma suspended above the active surface of the Sun by looping magnetic fields. Seen against the solar disk it looks dark only because it's a little cooler, and so slightly dimmer, than the solar photosphere. Suspended above the solar limb the same structure looks bright when viewed against the blackness of space and is called a solar prominence. A filaprom would be both of course, a stream of magnetized plasma that crosses in front of the solar disk and extends beyond the Sun's edge. In this hydrogen-alpha close-up of the Sun captured on June 22, active region AR3038 is seen at the right, close to the Sun's western limb. As AR3038 is carried by rotation toward the Sun's visible edge, what was once a giant filament above the active region is now partly seen as a prominence. How big is AR3038's filaprom? For scale planet Earth is shown near the top right corner.
