Space Weather Prediction Capability using SOHO LASCO and EIT

调查人员将确定SOHO航天器上的白光日冕仪和极端紫外线成像仪的太阳观测结果是否提供了指向地球的日冕物质抛射(CME)的明确信号。他们还将对这些观测数据进行统计研究，作为地磁风暴的预测指标。他们的方法是使用30个月的LASCO和EIT观测，将分析从现在发布的几个个别案例扩展到适合预测的一般规则。预报CME及其地磁后果的技术将直接惠及国家空间气象计划。该项目还应该为CME的三维结构提供科学见解。

The investigators will determine whether combined solar observations from a white light coronagraph and extreme ultraviolet imager on the SOHO spacecraft provide an unambiguous signature of an Earthward directed coronal mass ejection (CME). They will also perform a statistical study of these observations as a predictor of geomagnetic storms. Their approach is to use 30 months of LASCO and EIT observations to expand the analysis from a few individual cases now published into general rules suitable for forecasting. A technique for forecasting CME's and their geomagnetic consequences would directly benefit the National Space Weather Program. The project should also provide scientific insight into the three-dimensional structure of CME's.
