摘要：
Sunspots at their photospheric level show many interesting targets for the Visible-Light Imager and Magnetograph onboard the Solar Orbiter: Umbral dots and diffuse background, penumbral filaments, penumbral grains, and interactions of fine structures at umbral and penumbral borders. All these features require an extremely high spatial resolution both in imaging and in spectroscopy.
