活動太陽上的臨近帶和細絲
Prominences and Filaments on the Active Sun

這張經過著色和銳化處理的太陽影像由記錄 5 月 15 日太陽色球層氫原子發射的幀組成。在接近太陽週期 25 的最大值時，可以看到活躍的太陽表面出現了許多活躍區和蛇形扭曲的太陽細絲。 等離子體絲懸浮在活躍區的強磁場中，懸浮在太陽邊緣上方，呈現出明亮的太陽突出部。在太陽邊緣 4 點鐘附近和 9 點鐘之前看到的大型突出物是當天發生的兩次強烈 X 級太陽耀斑的耀斑後環流。事實上， 4 點鐘方向的突出與太陽邊緣旋轉的怪獸活動區 AR 3664 有關。
原文：This colorized and sharpened image of the Sun is composed of frames recording emission from hydrogen atoms in the solar chromosphere on May 15. Approaching the maximum of solar cycle 25, a multitude of active regions and twisting, snake-like solar filaments are seen to sprawl across the surface of the active Sun. Suspend in the active regions' strong magnetic fields, the filaments of plasma lofted above the Sun's edge appear as bright solar prominences. The large prominences seen near 4 o'clock, and just before 9 o'clock around the solar limb are post flare loops from two powerful X-class solar flares that both occurred on that day. In fact, the 4 o'clock prominence is associated with the monster active region AR 3664 just rotating off the Sun's edge.
