>>22286586also because there is no anode tufting where a spot is located, the voltage rise (region a to b in the energy plot above
>>22286572 ), which normally limits the local flow of positive ions leaving the anode surface, does not exist there.
In sunspots, then, a large number of ions will flood outward toward the lower corona.
Such a flow constitutes a large electrical current and, as such, will produce a strong localized magnetic field near the sunspot.
The Sun's corona is difficult to see except in solar eclipses and in X ray images.
This is because the corona is a "normal glow" discharge compared to the tufts which are in "arc mode".
In some X ray images of the Sun (pic related) we can see "coronal holes" large dark regions in the brighter image of the solar corona.
The bright regions in X-ray images of the corona indicate hotter, more energetic areas, these are mainly above the sunspot regions.
