This eerie landscape of incandescent plasma suspended in looping and twisted magnetic fields stretched toward the Sun’s eastern horizon on September 16. Captured through a backyard telescope and narrowband filter in light from ionized hydrogen, the scene finds bright plages near dark sunspots and a gigantic prominence lofted above the solar limb. Some 600,000 kilometers across, the magnetized plasma wall would dwarf worlds of the Solar System. Ruling gas giant Jupiter can only boast a diameter of 143,000 kilometers or so, while planet Earth’s diameter is less than 13,000 kilometers. Known as a hedgerow prominence for its appearance, the enormous structure is far from stable though, and such large solar prominences often erupt.

這幅詭譎的景觀，由懸浮在迴圈和扭曲的磁場中的螢光等離子體組成，於9月16日朝著太陽的東方地平線延伸。這幅畫面是透過後院望遠鏡和窄帶濾鏡捕捉到的，顯示了來自帶電氫的光線。畫面中明亮的光斑靠近黑暗的日斑，而一個巨大的日弧高高懸浮在太陽邊緣。這個約600,000公里寬的磁化等離子體牆壁可說是讓整個太陽系的行星都相形見絀。氣體巨星木星的直徑僅約143,000公里，而地球的直徑則不到13,000公里。這個結構因其外觀而被稱為「hedgerow prominence」，但它遠未穩定，這樣大型的太陽弧往往會發生爆發。
