Solar, Heliospheric and INterplanetary Environment (SHINE) Studies of Colliding Coronal Mass Ejections

这项工作的主要目标是识别和理解复杂行星际活动之前的碰撞日冕物质抛射（CME）：太阳高能粒子（SEP）事件，太阳风结构和成分变化，行星际抛射物，无线电爆发和磁暴。多个数据源将用于（1）识别、列出和表征CME相互作用，（2）调查碰撞后2-4天的太阳风特征，地球导向的CME，（3）识别表现出混合脉冲和渐进特征的大型SEP事件，并确定它们与碰撞CME的关系（如果有的话），（4）对CME之间的相互作用类型进行分类，（5）确定CME相互作用的发生和特征是否存在太阳周期依赖性。

The principal goal of this effort is to identify and understand colliding Coronal Mass Ejections (CMEs) preceding complex interplanetary activity: solar energetic particle (SEP) events, solar wind structure and composition variations, interplanetary ejecta, radio bursts, and geomagnetic storms. Multiple data sources will be employed to (1) identify, list, and characterize CME interactions, (2) investigate solar wind signatures 2-4 days following colliding, Earth-directed, CMEs, (3) identify large SEP events which exhibit mixed impulsive and gradual characteristics and determine their relation (if any) to colliding CMEs, (4) classify types of interactions between CMEs, and (5) determine if there are solar-cycle dependences of CME interaction occurrences and characteristics.
