This is the biggest Cycle 24 spot since the first one was seen on January 4th, 2008. This spot looks to have some staying power other than the “specks” we’ve seen winking on and off lately. No squinting to see this one, or wondering if it’s a dead pixel in the SOHO CCD imager or not.

The corresponding magnetogram image, seen here, is also quite pronounced. The polarity is correct, with the white “North” at the top. This spot grew quickly as it came around the rim into visibility. Watch this animation below:
At the same time, to the right of the image, at lower latitude, a new cycle 23 sunspot seems to be emerging, note it has a reveresed polarity from the larger SC24 spot. Solar cycle 23 just won’t give up it seems. SourceOnly registered users can write comments!
