The pips at SpaceWeather.com seems to have gone alternative in their reporting style:
SHAPE-SHIFTING SUNSPOT: Every time you look, sunspot 1271 has a new outline. For the past two days the active region has been in a constant state of change, altering its shape on an hourly basis. Click on the image for 48 hours of shape-shifting:

These rapid changes have caused the sunspot's magnetic field to criss-cross and tangle. The magnetic field now has a "beta-gamma" configuration that harbors energy for M-class (http://www.spaceweather.com/glossary/flareclasses.html?PHPSESSID=lpod2ott2mf024kbo0mr06ttl6) solar flares. Any such flares today would be approximately Earth-directed because the sunspot is not far from disk-center. Readers with sunspot telecopes (http://www.shopspaceweather.com/explore-scientific-white-light-solar-observer-system.aspx) are encouraged to monitor developments.
