although 句子的一个疑问

lilyhuang

885-sec 19-4 的一道题：
Sunpots, vortices of gas associated with strong electro-magnetic activity, appear on the surface of the Sun as dark spots although never sighted at the Sun's poles or equator.

这已经是正确的表达,但有一个疑问，although never sighted at....是修饰sunpots还是修饰dark spots??? 在我看来似乎两者均可以, 你们怎么看? 如果句子是被描述成：
although never sighted at the Sun's poles or equator, sunpots, vortices of gas associated with strong electro-magnetic activity, appear on the surface of the Sun as dark spots. 我觉得更合理。

Many thanks ahead!

应该修饰的是dark spots, 因为根据句意，是dark spots被看见，虽然这个dark spots是指sunpots。
不赞成修改后的句子，因为句子重心发生改变。although never sighted at the sun's poles or equator应该着重修饰的是dark spots

although 之后可以省略主谓吗?

当主句的主语与although引导的句子的主语一致, 可省略although句子的主语.
