Abstract

Studies on sunspots have a very long history mostly supported by ground-based observations. However, the detailed evolution of sunspot magnetic field structures are revealed by Hinode observations of accurate photospheric magnetic fields at high spatial resolution under the seeing-free conditions. After the launch of Hinode, the radiative three-dimensional magnetohydrodynamic simulations successfully demonstrated sunspots. The combination of good observations and simulations results in rapid advancement in our knowledge about sunspots. Especially, fine-scale structures in sunspots are commonly understood as a manifestation of the magneto-convection .

The rapid progress in our understanding of sunspots after the launch of Hinode proves that SOT provides us excellent data. We really appreciate all people who are involved in the development and operation of SOT.
