Well, SWPC did not name yesterday’s area so it remained a pore, and today it’s gone. This means that today we are on the verge of surpassing the previous longest spotless streak during this solar minimum. This is based on SWPCs GEOA reports.  The region that came around the Eastern limb first looked like the negative pole was leading.  this changed during the day when a positive area developed leading the region, now indicating that the polarization is consistent with a C25 area.  The area can still be seen in the images as a faculae in the 540nm image and a plage in the Ha and CaK.
