The investigators will continue the operation of, and analysis of data from, the western half of the Magnetometer Array for Cusp and Cleft Studies (MACCS) located in Arctic Canada. For the past eight years, the MACCS array of twelve magnetometers has provided critical information in support of studies of Earth's space environment. Because of the interaction of the solar wind with Earth's magnetic field, magnetic field lines at the boundary between interplanetary space and the magnetosphere map to the polar cusps, small regions near 75 degrees magnetic latitude at local noon in the northern and southern hemispheres. These cusp regions are the focus of much ground-based research because of their potential to provide diagnostics of plasma interactions along this remote and invisible boundary. Future scientific efforts using MACCS data will emphasize long-period ULF waves, dayside-nightside coupling, and transients such as sudden commencements, sudden impulses, traveling convection vortices, and magnetic impulse events, all of which appear to be driven by the solar wind and interplanetary magnetic field. The data reduction and analysis efforts associated with this project are highly suitable for undergraduate research participation, and it will build on currently strong programs of faculty and undergraduate student research. The study will benefit through collaboration with visiting scientists from Russia.

研究人员将继续对位于加拿大北极地区的尖瓣和裂缝研究磁力计阵列（MACCS）的西半部进行操作和数据分析。 在过去八年中，MACCS的12个磁强计阵列为支持地球空间环境研究提供了重要信息。 由于太阳风与地球磁场的相互作用，行星际空间和磁层之间边界的磁力线映射到极尖，即北方和南半球当地中午时磁纬75度附近的小区域。 这些尖端区域是许多地面研究的焦点，因为它们有可能沿着沿着这个遥远而不可见的边界提供等离子体相互作用的诊断。 未来使用MACCS数据的科学工作将强调长周期ULF波，昼侧-夜侧耦合和瞬变，如突然开始，突然脉冲，移动对流涡旋和磁脉冲事件，所有这些似乎都是由太阳风和行星际磁场驱动的。 与该项目相关的数据简化和分析工作非常适合本科生参与研究，它将建立在目前强大的教师和本科生研究计划的基础上。 这项研究将通过与俄罗斯访问科学家的合作受益。
