The eruption of a large prominence that occurred away of active regions in the SOL2013-09-29 event produced a fast coronal mass ejection (CME) and a shock wave. The event caused considerable geospace disturbances, including a proton enhancement that have been addressed in previous studies. Continuing with the analysis of this event, we focus on the development of the CME and shock wave, assess an expected geospace impact using simplest considerations, and compare the expectations with in situ measurements near Earth. The high CME speed in this non-flare-associated event was determined by a considerable reconnected flux that corresponds to a pattern established by different authors. Estimations based on a few approaches showed the reconnection flux in this event to be comparable with a typical value in flare-associated eruptions. The shock wave was most likely impulsively excited by the erupting prominence in the same way as in flare-associated events and changed to the bow-shock regime later. The trajectory calculated for this scenario reproduces the Type II emission observed from 30 MHz to 70 kHz; its interruptions were probably caused by propagation effects. Properties of the near-Earth proton enhancement are discussed considering the results of recent studies.

2013 年 9 月 29 日静止突起喷发引起的地质效应 CME

在 SOL2013-09-29 事件中，远离活动区域的大日珥的喷发产生了快速日冕物质抛射 (CME) 和冲击波。该事件引起了相当大的地球空间扰动，包括先前研究中已经解决的质子增强。继续分析这一事件，我们关注 CME 和冲击波的发展，使用最简单的考虑评估预期的地球空间影响，并将预期与地球附近的现场测量进行比较。这种非耀斑相关事件中的高 CME 速度是由相当大的重新连接通量决定的，该通量对应于不同作者建立的模式。基于几种方法的估计表明，该事件中的重联通量与与耀斑相关的喷发的典型值相当。冲击波很可能被爆发的日珥以与耀斑相关事件相同的方式冲动激发，后来转变为弓形冲击状态。为这种情况计算的轨迹再现了从 30 MHz 到 70 kHz 观察到的 II 类发射；它的中断可能是由传播效应引起的。考虑到最近的研究结果，讨论了近地质子增强的特性。
