The main goal of this 3-year SHINE project is to study the locations of the type II radio bursts at frequencies around and below 1 MHz by utilizing measurements from the Wind/WAVES and STEREO/WAVES radio instruments. The obtained radio source locations will be compared with the white-light images of Coronal Mass Ejections (CMEs) taken by the SOHO/LASCO and STEREO/SECCHI coronagraphs and heliospheric imagers. This research project will shed more light on the origin of the type II radio emissions during CME events and related shock waves. Furthermore, the project team aims to test the validity of various theoretical models of the type II radio bursts. This research project contributes to broader societal activities, such as advancing the participation of women in science and improving the scientific literacy of the general public. The project team will present the results of this research project at national scientific meetings and will publish them in peer-reviewed scientific journals. In addition, the team will setup and maintain a website, where all relevant data for each analyzed radio event will be made available to the general public. The research and EPO agenda of this SHINE project supports the Strategic Goals of the AGS Division in discovery, learning, diversity, and interdisciplinary research.

这一为期3年的SIRE项目的主要目标是利用风/波和立体声/波无线电仪器的测量结果，研究频率在1兆赫及以下的第二类射电爆发的位置。获得的射电源位置将与SOHO/LASCO和STEREO/SECCI日冕成像仪拍摄的日冕物质抛射(CME)的白光图像进行比较。这项研究项目将进一步阐明CME事件和相关冲击波期间第二类射电辐射的来源。此外，项目组的目标是测试II型射电爆发的各种理论模型的有效性。这一研究项目有助于更广泛的社会活动，如促进妇女参与科学和提高公众的科学素养。项目组将在国家科学会议上介绍这一研究项目的成果，并将在同行评议的科学期刊上发表。此外，该小组将建立和维护一个网站，在该网站上将向公众提供每个分析的无线电事件的所有相关数据。该项目的研究和EPO议程支持AGS部门在发现、学习、多样性和跨学科研究方面的战略目标。
