Magnetic Connections of Solar Formations Inside Magneto-Isolated Complexes Based on Observations of Arch Structures and Calculations of Magnetic Field Lines

摘要

The magnetic connections of solar formations inside magneto-isolated complexes with areas outside the complexes were determined from the loop structures in the upper chromosphere and corona, as well as from calculations of magnetic field lines. It was found that 65% of the constructed field lines are closed within complexes or not closed on the solar surface, while 35% of the field lines intersect the boundary of the complex. Short field lines that intersect the boundary of the complex often connect the points of low intensity. The ends of the long field lines coincide with ends of the arch structures, whose higher parts are not visible in the 17.1 nm line. The short field lines coincide in position with the loop structures at the corona level. It was shown that there are three types of magnetic field variations depending on the height above the complexes.
