论文摘要
过去,有许多研究声称地磁风暴的作用在很大程度上取决于冠状质量弹出(CMES)的磁云部分的方向。 Aparna&Martens(2020)使用2007 - 2017年的Halo-CME数据,表明,在CMES起源的位置的细丝的磁场方向可有效地用于预测地球磁风暴的发作。这项研究的目的是通过分析1996 - 2006年的Halo-CME数据来扩展其调查。灯丝轴向方向及其相应的BZ特征的相关性用于为Aparna&Martens提出的主张形成更广泛的推理。这项研究利用了时间段的SOHO EIT195Å,MDI磁图图像,KSO和BBSO H $α$图像,以及用于行星际磁场签名的ACE数据。与所有这些相关联,我们发现Aparna&Martens研究轴向场方向与BZ方向之间相关性很可能的趋势仍然存在于1996 - 2006年之间的数据。
In the past, there have been many studies claiming that the effects of geomagnetic storms strongly depends on the orientation of the magnetic-cloud part of the Coronal Mass Ejections (CMEs). Aparna & Martens (2020), using Halo-CME data from 2007-2017, have shown that the magnetic field orientation of filaments at the location where CMEs originate can be effectively used for predicting the onset of geo-magnetic storms. The purpose of this study is to extend their survey by analyzing the halo-CME data for 1996-2006. The correlation of filament axial direction and their corresponding Bz signatures are used to form a more extensive reasoning for the claims presented by Aparna & Martens before. This study utilizes SOHO EIT 195 Å, MDI magnetogram images, KSO and BBSO H$α$ images for the time period, along with ACE data for inter-planetary magnetic field signatures. Correlating all these, we have found that the trend in Aparna & Martens' study of a high likelihood of the correlation between the axial field direction and Bz orientation, persists for the data between 1996-2006 as well.
