Fig.
12 Another example of preflare
plasma at microwaves. On the multiwaves scans two AR’s are
|
|
|
|
presented.
Near the solar meridian the stable AR and near the West-limb the FPAR 9393 are located.

The
microwave emission of FPAR demonstrates the frequency domain (the
wavelengths from 2.47
|
|
|
|
cm to
3.21 cm) with low polarization degree, which shown on the right in big
scale also. The sharp

structural
changes one can see in narrow frequency band. The powewrful flare X 14.0
