SWAP对2014年10月14日长持续太阳爆发后耀斑巨拱的观测
SWAP Observations of Post-flare Giant Arches in the Long-Duration 14 October 2014 Solar Eruption
摘要：
2014年10月14日，PROBA 2号航天器上的太阳观察者与主动像素和图像处理（SWAP）极紫外太阳望远镜观测到了一次喷发，这可能是第24太阳周期日冕中最大的喷发后环系统。第一次喷发发生在10月14日18：30，在东太阳边缘的后面，被观测到一次日冕物质抛射和一次M2.2的太阳耀斑。在爆发后的48小时内，相关的爆发后环以2-6 km/s的速度增长到大约400000 km（>0.5太阳半径）的高度。我们的结论，从我们的观察，这一事件，普通的爆发后的环和所谓的耀斑后的巨型拱门是基本相同的，是由相同的磁重联机制。
英文摘要：
On 14 October 2014 the Sun Watcher with Active Pixels and Image Processing (SWAP) EUV solar telescope on-board the Project for On-Board Autonomy 2 (PROBA2) spacecraft observed an eruption that led to the formation of perhaps the largest post-eruptive loop system seen in the solar corona in solar cycle 24. The initial eruption occurred at about 18:30 UT on 14 October, behind the East Solar limb, and was observed as a a coronal mass ejection and an M2.2 solar flare. In the 48 hours following the eruption, the associated post-eruptive loops grew to a height of approximately 400000 km (>0.5 solar-radii) at rates between 2-6 km/s. We conclude from our observations of this event that ordinary post-eruptive loops and so-called post-flare giant arches are fundamentally the same and are formed by the same magnetic reconnection mechanism.
