The Principal Investigator (PI) plans to investigate how erupting solar filaments and Coronal Mass Ejections (CMEs) are triggered. The research will focus on why and how quiescent filaments frequently erupt when a new solar active region (AR) occurs within a broad area up to 35 heliographic degrees from middle of the quiescent filament. This relationship was first noted by Bruzek in 1952, and past statistical studies have verified its validity. The PI's team will examine new spacecraft data for evidence of interactions among solar coronal magnetic fields that could explain the Bruzek relationship. Specifically, the PI's team will use wavelet processed images from the Solar Heliospheric Observatory Extreme-ultraviolet Imaging Telescope (SOHO EIT) instrument to investigate how an AR can serve as a catalyst for a quiescent filament to erupt, even when such a filament is relatively distant from the newly forming AR. The PI will analyze a sample of at least 50 specific events while focusing on observed evidence of magnetic interactions. The PI expects this research to stimulate the development of new approaches to modeling erupting solar filaments and CMEs, which will not only be very useful for the solar physics research community, but also provide practical benefits to society. Such results will improve forecasts of erupting filaments and CMEs, which are important for space weather operations. One undergraduate student will assist in the planned data analysis during the summer months in each year of the project.This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).

首席研究员（PI）计划研究如何触发爆发的太阳细丝和日冕物质抛射（CME）。这项研究将集中在为什么以及如何静态灯丝频繁爆发时，一个新的太阳活动区（AR）发生在一个广泛的区域内高达35日像度从中间的静态灯丝。Bruzek在1952年首次注意到这种关系，过去的统计研究已经验证了它的有效性。PI的团队将检查新的航天器数据，以寻找太阳日冕磁场之间相互作用的证据，这些证据可以解释Bruzek关系。 具体来说，PI的团队将使用来自太阳日光层天文台极紫外成像望远镜（SOHO EIT）仪器的小波处理图像来研究AR如何作为静止灯丝爆发的催化剂，即使这样的灯丝距离新形成的AR相对较远。PI将分析至少50个特定事件的样本，同时重点关注观察到的磁相互作用证据。PI希望这项研究能够刺激新方法的发展，以模拟爆发的太阳能灯丝和CME，这不仅对太阳物理研究界非常有用，而且还为社会提供实际利益。这类结果将改进对空间气象业务十分重要的爆发丝状体和日冕物质抛射的预报。一名本科生将在项目每年的夏季协助计划中的数据分析。该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。
