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

这项工作的主要目标是确定和了解在复杂的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、星际抛射、射电爆发和地球磁暴。将使用多个数据来源来(1)确定、列出和描述日冕物质抛射相互作用，(2)调查碰撞后2-4天的太阳风特征，(3)查明表现出冲动性和渐进性混合特征的大型SEP事件，并确定其与碰撞日冕物质抛射的关系(如果有)，(4)对日冕物质抛射之间相互作用的类型进行分类，以及(5)确定日冕物质抛射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.
