This data-analysis project investigates the phenomenology of "the calm before the storm", which are intervals of very weak geomagnetic activity that often occur prior to the high-speed solar wind streams that drive geomagnetic storms. A typical calm interval has a duration of two days. The objectives of this project are to determine (1) whether the calm before the storm is a systematically occurring or a randomly occurring phenomena, (2) what properties of the solar wind give rise to the calms, and (3) what the effects of the calms are on the ensuing geomagnetic storms. The primary data sources that will be used are the solar wind data from the ACE satellite and the particle flux data provided by the Los Alamos geosynchronous satellites. Additional data that will be used are the standard magnetic indices, Kp, Dst, and AE. The project involves both solar-wind research and magnetospheric-physics research. It will advance the understanding of fundamental processes that affect the Earth's magnetosphere and space weather. The project will also participate in an ongoing summer outreach program for science teachers that is held each summer at Los Alamos.

这个数据分析项目调查了“风暴前的平静”现象，这是非常微弱的地磁活动的间隔，通常发生在驱动地磁风暴的高速太阳风流之前。典型的平静期持续两天。该项目的目标是确定(1)风暴前的平静是系统发生的还是随机发生的现象；(2)太阳风的什么特性导致了平静；(3)平静对随后的地磁风暴有什么影响。将使用的主要数据来源是ACE卫星提供的太阳风数据和洛斯阿拉莫斯地球同步卫星提供的粒子通量数据。将使用的附加数据是标准磁指数，Kp， Dst和AE。该项目包括太阳风研究和磁层物理研究。它将促进对影响地球磁层和空间天气的基本过程的理解。该项目还将参加每年夏天在洛斯阿拉莫斯举行的科学教师暑期拓展计划。
