Magnetic field compression over a sunspot
Abstract
A simple model is proposed to explain the effect sometimes observed over or near a sunspot when the magnetic field strength at the chromospheric level appeared to be greater than the photospheric field. The model is a uniformly twisted magnetic flux tube with 'corrugated' magnetic surfaces. It is proposed that the magnetic field in the chromosphere can be compressed to a few kilogauss.
