Magneto-isolated complexes at two levels of the solar atmosphere

The magneto-isolated complexes were found in the upper chromosphere from observations in the He I λ 1083 nm line. All the complexes were confidently identified in the corona from the images in the FeIX-X λ 17.1 line. The boundaries of the complexes at two heights are always visible in the form of channels. Their width depends on the structures located close to the borders inside and outside the complex. Most arch structures, one end of which is located inside the complex, do not cross the boundaries of the complexes (70 % at the upper chromosphere and 80 % of events at the corona). 80 % of the coronal holes appearing in the complexes have an open structure of the magnetic field.
