论文摘要
在2017年期间,当太阳朝着太阳能周期的最小阶段转向24的最低阶段时,在8月28日至9月10日的8月28日在阳光下出现了一个异常爆发的活动区域(AR)NOAA 12673。在最高的活动水平上,AR变成了三角洲型太阳斑点区域,这表现出了从Photosphere for Photosphere和Coronal forcoronal forcoronal for Coronal for coronal for coronal for coronal for coronal forcoronal forcoronal the coronal type。 The AR 12673 produced four X-class and 27 M-class flares, along with numerous C-class flares, making it one of the most powerful ARs of solar cycle 24. Notably, it produced the largest flare of solar cycle 24, namely, the X9.3 event on 2017 September 6. In this work, we highlight the results of our comprehensive analysis involving multi-wavelength imaging and coronal magnetic field modeling to understand the evolution and eruptivity从AR 12673开始。我们特别关注2017年9月6日这两种X级耀斑的形态,光谱和运动学演化。我们探索了有效区域的各种大型和小型磁场结构,这些磁场结构与强大的太阳能瞬态期间的触发和后续爆发有关。
During 2017, when the Sun was moving toward the minimum phase of solar cycle 24, an exceptionally eruptive active region (AR) NOAA 12673 emerged on the Sun during August 28-September 10. During the highest activity level, the AR turned into a delta-type sunspot region, which manifests the most complex configuration of magnetic fields from the photosphere to the coronal heights. The AR 12673 produced four X-class and 27 M-class flares, along with numerous C-class flares, making it one of the most powerful ARs of solar cycle 24. Notably, it produced the largest flare of solar cycle 24, namely, the X9.3 event on 2017 September 6. In this work, we highlight the results of our comprehensive analysis involving multi-wavelength imaging and coronal magnetic field modeling to understand the evolution and eruptivity from AR 12673. We especially focus on the morphological, spectral and kinematical evolution of the two X-class flares on 6 September 2017. We explore various large- and small-scale magnetic field structures of the active region which are associated with the triggering and subsequent outbursts during the powerful solar transients.
