Bearclaw Sunspot
Imagine a bear claw with toes the size of Earth. Yesterday, Philippe Tosi of Nîmes, France, looked through the eyepiece of his solar telescope and saw exactly that:
Magnetic fields criss-crossing the toes and pad of this Ursidamorphic structure harbor energy for M- and X-class solar flares. However, the sunspot has been quiet for almost three days, so NOAA forecasters are estimating a relatively low 5% chance of X-flares on Nov. 20th.
