太阳活动区AR 12975中X1.3级耀斑事件分析
|
Abstract:
基于多波段观测数据，分析2022年3月30日太阳活动区NOAA AR 12975中爆发的X1.3级耀斑。耀斑发生期间活动区出现了S型结构与明显的光斑，同时活动区里出现的白色局部斑状光亮，可以看到明显的亮度提升，白色局部斑状光亮逐渐演变为明亮的耀斑带。两条耀斑带相互接近，发生重联现象，之后形成大型拱顶结构，两端脚点的耀斑带向外拓展；到最后拱顶结构断开，南北脚点的耀斑带停止了延伸。从磁场能量的角度看，早在耀斑出现在太阳表面时，活动区的磁场活跃强度就在逐渐加剧。在不同的M级耀斑与C级耀斑事件发生后，活动区AR 12975的磁场强度不减反增，预示了接下来即将发生的大型耀斑爆发。结合多维演变图像分析，我们得出结论：活动区AR 12975可以被视为一个良好的测试对象，用来研究光球磁场活动在触发强大太阳爆发中的作用。
Based on multi-band observation data, the X1.3 flare that erupted in NOAA AR 12975 in the active region of the solar surface on March 30, 2022 was analyzed. During the flare, the S-shaped structure and obvious light spots appeared in the active area, and the white local spotted light appeared in the active area, and the brightness of the white local spotted light gradually evolved into a bright flare band. The two flare zones are close to each other and reconnect, and then a large vault structure is formed, and the flare zones at the feet of both ends expand outward. By the end of the vault structure was disconnected, and the flare bands at the north and south foot points stopped extending. From the perspective of magnetic field energy, as early as the appearance of flares on the surface of the sun, the active intensity of the magnetic field in the active region is gradually increasing. After the occurrence of different M-class flare and C-class flare events, the magnetic field strength of AR 12975 in the active area did not decrease but increased, indicating that the next large-scale flare outbreak was about to occur. Combined with the analysis of multi-dimensional evolutionary images, we conclude that the active region AR 12975 can be considered as a good test object for studying the role of photosphere magnetic field activity in triggering powerful solar bursts.
