It should be emphasized that the large-scale chains under consideration are relatively weak features as a rule. Perhaps, it is one of reasons why these structures have been not discovered so far. To distinguish them on the solar images, including many other features, one should to examine the images with a considerable attention.
It should be noted also, that usually the blobs and bright points form many various complicated (sometimes crossing) chains and structures on the disc. Sometimes it is not so easy to outline the concrete chains and structures unambiguously. Therefore we will consider here only those chains and structures which predominate and are distinguished evidently.
!!! Please note that the images presented here are for a review only, but the corresponding simplified files are not intended for printing of the qualitative pictures.
