Space Weather Prediction Capability using SOHO LASCO and EIT

研究人员将确定SOHO航天器上的白光日冕仪和极紫外成像仪的太阳观测是否能提供向地球定向日冕物质抛射（CME）的明确信号。他们还将对这些观测结果进行统计研究，作为地磁风暴的预测指标。他们的方法是利用LASCO和EIT 30个月的观察结果，将目前已发表的少数个别案例的分析扩展为适用于预测的一般规则。一种预测日冕物质抛射及其地磁影响的技术将直接有利于国家空间天气计划。该项目还将为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.
