From the relative locations of the 2 and 3.6 cm sources, the magnetic field gradient and the total magnetic field was determined. These seem to be the radio counterparts of polar plumes. The brightness temperature of the PRS is less than the coronal temperature so a thermal emission mechanism may suffice to explain the observations. The polar plumes are thought to be associated with bright points which are bipolar magnetic regions. It is possible that superthermal particles are produced due to reconnections in these bipolar fields, resulting in weak nonthermal emission.
Nonthermal emission is also consistent with the time variability of the polar radio sources.
The large scale structure was observed in microwaves. Ejection of plasmoids from the bright point flare site into the large scale structure was also observed. The large scale structure was cold and not visible in X-rays. The superhot component with a temperature of 32 MK was observed in hard X-ray images and in light curves during the impulsive phase of the flare with possible radio signatures at 20 cm wavelength. This was found to be a major confined flare as there was no radio emission at any frequency below 1.4 GHz.
