我们报告的第一次观察到的一个单一的混合磁结构，包含一个伪流光和双流光。这个结构最初是由PROBA 2卫星上的SWAP仪器在2013年5月5日至10日之间观测到的。它由一对靠近太阳南极的暗条通道组成。在该结构的西边缘，磁丝上方的磁形态是并排的双流光，两个通道之间有开放的磁场。在东部边缘，磁形态是一个没有中央开放场的日冕伪流光。我们研究了这种结构与多个观察和建模技术。我们描述这样一个统一的结构的拓扑结构和动态后果。
We report on the first observation of a single hybrid magnetic structure that contains both a pseudostreamer and a double streamer. This structure was originally observed by the SWAP instrument on board the PROBA2 satellite between 2013 May 5 and 10. It consists of a pair of filament channels near the south pole of the Sun. On the western edge of the structure, the magnetic morphology above the filaments is that of a side-by-side double streamer, with open field between the two channels. On the eastern edge, the magnetic morphology is that of a coronal pseudostreamer without the central open field. We investigated this structure with multiple observations and modeling techniques. We describe the topology and dynamic consequences of such a unified structure.
