This collaborative project will continue the analysis of data obtained by a network of autonomous magnetometers deployed on the antarctic continent by the British Antarctic Survey (BAS). The magnetometers provide information on the interaction of the solar wind with the Earth's magnetic field, an area of research that is particularly important in the context of space weather, and the effect of solar events on the operation of satellites and ground-based electronic systems. The data analysis will be a collaborative project among scientists at Augsburg College, the University of New Hampshire, and at BAS, and will focus especially on ultra-low frequency (ULF) waves and transients. In particular on Pc1 and Pc2 waves, both dayside events triggered by sudden increases in the solar wind dynamic pressure, and dawn-side events apparently related to the injection of ions from the magnetotail. Studies of irregular ULF waves, especially during magnetic storms and substorm periods are a further area of interest. These analysis efforts are highly suitable for undergraduate research participation and build on currently strong programs of faculty and student research.

这一合作项目将继续分析英国南极调查局在南极大陆部署的自主磁力仪网络所获得的数据。磁力计提供关于太阳风与地球磁场相互作用的信息，这是一个在空间天气方面特别重要的研究领域，以及太阳事件对卫星和地面电子系统运行的影响。数据分析将是奥格斯堡学院、新汉普郡大学和BAS的科学家合作的项目，将特别关注超低频(ULF)波和瞬变。特别是在Pc1和Pc2波上，这两种事件都是由太阳风动压突然增加引发的日侧事件，以及显然与磁尾离子注入有关的黎明侧事件。对不规则的超低频波，特别是在磁暴和亚暴期间的研究是另一个令人感兴趣的领域。这些分析工作非常适合本科生的研究参与，并建立在目前强大的教职员工和学生研究计划的基础上。
