Support for two specific data analysis investigations is requested. The first is an investigation of dayside aurora and associated measurements of magnetopause locations obtained from simultaneous ground based and satellite measurements. They expect to be able to distinguish between magnetopause motions which result from changes in dynamic pressure and those due to flux erosion and hypothesize that dayside auroral motions are associated only with the latter. The second is a large statistcal investigation of a large database of magnetopause crossings to extablish the relationship between changes in magnetopause location and substorm activity.

请求为两项具体的数据分析调查提供支持。第一项是调查日侧极光以及从地面和卫星同时测量获得的磁层顶位置的相关测量结果。他们希望能够区分由动力压力变化引起的磁层顶运动和由磁通量侵蚀引起的磁层顶运动，并假设白天的极光运动只与后者有关。第二项是对磁层顶交叉点的大型数据库进行大规模统计调查，以建立磁层顶位置变化与亚暴活动之间的关系。
