Radio Measurements of Coronal Magnetic Fields

The measurement of magnetic field strengths in the solar corona using radio observations is reviewed. This is a well established technique that exploits the fact that the electron gyrofrequency for typical coronal magnetic field strengths (100–2000 Gauss) lies in the radio frequency range. Opacity from the resulting gyroresonance emission from hot plasma above active regions allows the direct m...

On the Discrepancy of Coronal Magnetic Fields in Solar Optics and Radio

It is analysed the discrepancy about the coronal magnetic eld between solar optic and solar radio using magnetic bril concept with lling factor and fractal structure model. The magnetic eld of 100 G considered in solar optics is mean value in a large scale, and that of 1000 G in solar should be the value of ne structures inside \macro" loop. The magnetic eld in the solar corona is poorly known ...
