论文摘要
我们描述了在活性区域NOAA 12348的前面的黑子中观察到的黑子阴茎扇区的消失及其恢复过程。磁场的演变和等离子体流的演变支持了由于盖盖磁场倾斜的变化而形成的磁场的观念。在黑子半月界的崩解阶段已经观察到了移动的磁特征。在恢复阶段，我们尚未观察到黑子周围的任何磁通量出现。半身部部门的恢复过程在大约72小时内完成，并伴随着从反式流向经典的Evershed流量的过渡。 IBIS进行的光电光谱测量值的反转使我们能够重建磁场的未梳状构型在新的阴茎新沉降过程中如何形成，即磁场的垂直成分似乎被某些水平场线逐渐替换为与内部的水平线。
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.
