SWAN25B是指一顆於2025年9月11日由弗拉基米爾·貝祖格利（Vladimir Bezugly）透過SWAN影像發現的非週期彗星之臨時編號。截至2025年9月14日，該彗星目前視星等約為6.9等，太陽距角為30度，可透過50毫米雙筒望遠鏡在角宿一附近觀測[1]。此彗星可能正處於爆發階段，其暗淡速度或是否會完全解體尚屬未知。


==
 SWAN25B  彗星目前仍在待確認名單中  ，但是已經有明顯彗髮及長 2.8° （！？）的彗尾，亮度 7.4 等（！？）。不意外地，將直接躋身全天最亮彗星。

SWAN25B彗星目前位置正在室女座，往日落後的西方天空看去大約位在火星與角宿一的右下方。接著SWAN25B彗星會往天秤座方向移動，並預計在10月初抵達，日落後的彗星位置仰角也會越來越高。有觀測者宣稱在10月初彗星將以0.25AU的距離通過地球旁邊，屆時可能會引發流星雨出

今天許多彗星影像證實了彗髮形狀變成了三角形（遠離彗尾一側寬、靠近彗尾一側收束），這種「三角頭、鐵錘頭」是過去許多彗星彗核分裂的前兆
