Height Structures of Magnetic Fields in Solar Active Regions.
The methods of multiwavelength radio astronomy have shown that over the solar spots the magnetic fields with the strength of approximately 1000G are measured at rather large heights in the solar atmosphere (from 10 to 25 thousand km), which is confirmed by the space observatory observations in the ultraviolet lines of magnetic loops. These data contradict the conventional models of the magnetic field; hence we have to use the models for a very structured and twisted vertical magnetic field over the spot.
In collaboration with SPBU.
