| Abstract: |
The formation of moving magnetic features (MMFs) separating from the penumbra were successfully observed with the Solar Optical Telescope (SOT) aboard the Hinode satellite. We find that bright features in the outer penumbra are located at the penumbral spines, which have magnetic fields more vertical than the surroundings, or located at the MMFs separating from the spines. This suggests that convection in the outer penumbra is related to the disintegration of the sunspot. |
