A long solar filament stretches across the relatively calm surface of the Sun in this telescopic snap shot from April 27. The negative or inverted narrowband image was made in the light of ionized hydrogen atoms. Seen at the upper left, the magnificent curtain of magnetized plasma towers above surface and actually reaches beyond the Sun’s edge. How long is the solar filament? About as long as the distance from Earth to Moon, illustrated by the scale insert at the left. Tracking toward the right across the solar disk a day later the long filament erupted, lifting away from the Sun’s surface. Monitored by Sun staring satellites, a coronal mass ejection was also blasted from the site but is expected to swing wide of our fair planet.

一條長長的太陽暗條在相對平靜的太陽表面伸展著，這幅攝影作品拍於4月27日。這幅負片的狹帶影像是透過電離氫原子的光線拍攝的。攝影圖的左上方可見，這幅雄偉的磁場等離子幕高高懸起，實際上還超出了太陽的邊緣。這條太陽暗條的長度大約與地球到月球的距離相等，左側顯示了比例插圖。一天後，當我們向右橫越太陽盤面時，這條長暗條發生了爆發，開始脫離太陽表面。這次事件由監察太陽的衛星進行了追蹤，並且從該地點也噴發出了日冕物質拋射，但預計會偏離我們的星球。
