The objective of this project is to obtain continuous, global, real-time monitoring of the auroral size, configuration, and dynamics for use in space weather specification and warning systems and for near-term forecasting as an input to global circulation models. The method is based upon the observation that 0.1 - 100 Hz magnetic fluctuations appear to be a good identifier of the auroral oval at satellite altitudes. It may be possible then to utilize non-science grade magnetometers used for attitude determination on the suites of commerical communication and navigation satellites to provide continuous monitoring of the auroral oval. The project will undertake a more thorough investigation of the magnetic fluctuations and will examine test data from the RIDIUM attitude magnetometer to test the efficacy of the proposed method.

该项目的目标是获得对极光大小、配置和动态的连续、全球、实时监测，用于空间天气规范和预警系统以及近期预报，作为全球环流模型的输入。 该方法基于以下观察：0.1 - 100 Hz 磁波动似乎可以很好地识别卫星高度处的极光椭圆形。 然后，可以利用用于商业通信和导航卫星套件上的姿态确定的非科学级磁力计来提供对极光椭圆形的连续监测。 该项目将对磁波动进行更彻底的研究，并将检查 RIDIUM 姿态磁力计的测试数据，以测试所提出方法的有效性。
