The investigators will extract solar wind information and locate potential Coronal Mass Ejection (CME) sites at the sun from sequences of low spatial resolution synoptic maps derived from magnetograms. Their approach is to use the publicly available GONG (Global Oscillation Network Group) data archive to upgrade the time resolution and coverage of an established technique. GONG is a community-based project primarily intended to conduct a detailed study of solar internal structure and dynamics using helioseismology. The GONG distributed-site data will allow frequent (20 minute) sampling of the solar magnetic field with reduced influence from local troposphere (as opposed to space) weather or night time.

研究人员将提取太阳风信息，并从来自磁图的低空间分辨率天气图序列中定位太阳上潜在的日冕物质抛射（CME）地点。他们的方法是使用公开可用的GONG（全球振荡网络组）数据档案来升级现有技术的时间分辨率和覆盖范围。GONG是一个以社区为基础的项目，主要目的是利用日震学对太阳内部结构和动力学进行详细研究。GONG分布式站点数据将允许对太阳磁场进行频繁（20分钟）采样，减少当地对流层（而不是空间）天气或夜间的影响。
