摘要
We study a possible connection of moving magnetic features (MMFs) and the overlying atmosphere using several sets of multiwavelength observations of sunspot areas from the photosphere to the corona. We find that as a collective phenomenon, very intense MMF formation anticorrelates with the presence of large-scale "stable" coronal loops: such loops are rooted at the side of sunspots with no or few MMFs rather than at the side of the penumbra/moat highly populated by MMFs. Conjectures to help understand the observed correlation between the preferable site of coronal loops and the deficiency of MMFs are discussed.
