The capabilities of the LOw Frequency ARray (LOFAR) for the observation of solar transient events such as coronal mass ejections (CMEs) and for mapping of density and velocity structures in the inner heliosphere will be ascertained. The necessary requirements for LOFAR to contribute to space weather studies will subsequently be determined. An exploration of the feasibility of determining the magnetic field within a CME, by Faraday rotation of the polarization of cosmic sources, will be conducted. This would provide a novel and extremely important input to the determination of the geo-effectiveness of CMEs impacting the magnetosphere. These activities will contribute to the development of advanced remote sensing instrumentation for improved detection and understanding of key space weather phenomena.

将确定低频阵列射线观测日冕物质抛射等太阳瞬变事件和绘制日光层内部密度和速度结构图的能力。 随后将确定LOFAR对空间气象研究作出贡献的必要要求。 将进行一项探索，探讨通过宇宙源极化的法拉第旋转来确定日冕物质抛射内磁场的可行性。 这将为确定撞击磁层的日冕物质抛射的地球有效性提供一种新的、极其重要的投入。 这些活动将有助于开发先进的遥感仪器，以改善对关键空间天气现象的探测和了解。
