五颗明亮的彗星在这些面板上进行了比较，由长寿的、凝视太阳的SOHO航天器上的日冕仪记录下来。按时间顺序排列，它们的尾巴在每个视场的中心远离太阳，在那里，对极其明亮的太阳的直接观察被日冕仪的掩星盘挡住了。每一颗彗星对地球上的天文观测者来说都是难忘的，从左上角的麦克诺特彗星开始，它是21世纪迄今为止最亮的彗星。C/2023 A3 Tsuchinshan-ATLAS，在它的近日点与活动的太阳在底部中央，最近吸引了全球彗星观察者的注意。到2024年10月底，第6个空白面板可能会被明亮的掠日彗星C/2024 S1 (ATLAS). ...填满与否。

Five bright comets are compared in these panels, recorded by a coronograph on board the long-lived, sun-staring SOHO spacecraft. Arranged chronologically all are recognizable by their tails streaming away from the Sun at the center of each field of view, where a direct view of the overwhelmingly bright Sun is blocked by the coronagraph's occulting disk. Each comet was memorable for earthbound skygazers, starting at top left with Comet McNaught, the 21st century's brightest comet (so far). C/2023 A3 Tsuchinshan-ATLAS, following its perihelion with the active Sun at bottom center, has most recently grabbed the attention of comet watchers around the globe. By the end of October 2024, the blank 6th panel may be filled with bright sungrazer comet C/2024 S1 (ATLAS). ... or not.
