标题： Restoring process of sunspot penumbra

摘要： 我们描述了活跃区域 NOAA 12348 中前导太阳黑子的太阳黑子本影区域的消失及其恢复过程。磁场和等离子体流动的演化支持了这样的观点，即本影是由于覆盖层磁场倾斜角度的变化形成的。在该本影区域的分解阶段观察到了移动磁性特征。在恢复阶段，我们没有观察到太阳黑子周围有任何磁通量涌现。本影区域的恢复过程大约用了72小时，并伴随着从反向埃弗谢德流向经典埃弗谢德流的转变。通过IBIS获取的光球光谱偏振测量的反演，使我们能够重建本影新形成时磁场的未梳理配置，即磁场的垂直分量似乎被一些水平场线逐步取代，这些水平场线对应于脊内结构。 显示英文摘要

摘要： We describe the disappearance of a sector of sunspot penumbra and its restoring process observed in the preceding sunspot of active region NOAA 12348. The evolution of the magnetic field and the plasma flows support the idea that the penumbra forms due to a change of inclination of the magnetic field of the canopy. Moving magnetic features have been observed during the disintegration phase of that sector of sunspot penumbra. During the restoring phase we have not observed any magnetic flux emergence around the sunspot. The restoring process of the penumbra sector completed in about 72 hours and it was accompanied by the transition from the counter-Evershed flow to the classical Evershed flow. The inversion of photospheric spectropolarimetric measurements taken by IBIS allowed us to reconstruct how the uncombed configuration of the magnetic field forms during the new settlement of the penumbra, i.e., the vertical component of the magnetic field seems to be progressively replaced by some horizontal field lines, corresponding to the intra-spines.
