... volgens Jan Alvestad op http://www.dxlc.com/solar/.
Volgens hem is deze vlek in staat flares van klasse X10 en hoger te produceren. Blijkbaar dus een Vlek om U tegen te zeggen, zie ook volgend stukje (sorry voor het Engels). En nu maar duimen opdat de komende nachten beetje helder verlopen
"Region 10720 developed with the single penumbra expanding into the largest penumbra observed during solar cycle 23. Within this penumbra there are two major areas with negative polarity, one in the northeast and northern central part and another in the northwest. Both of these areas have long neutral inversion lines to the extremely strong positive polarity field in the south. That positive polarity area has the longest and largest umbra I have ever observed. At its western end this umbra is actually in contact (no space between) with the negative polarity umbra in the northwestern part of the penumbra. This is causing exceptional magnetic shear and extremely energetic flares, above the X10 class level, are possible. This region has the potential to generate flares similar to those observed in October/November 2003."
