geomagnetic

The resulting solar storm could cause a geomagnetic storm on Earth, knocking out electricity grids around the world for hours, days, or even months, bringing much of normal life grinding to a halt..由其引发的太阳风暴可能会激发地磁场风暴，届时，全球电网瘫痪，时间将长达数小时，数天，甚至几个月，大量的生产生活将无法继续进行。

The solar ejections that cause auroras can also create geomagnetic storms that can affect spacewalking astronauts, Earth-orbiting satellites, and even communications and power systems on the ground..引起极光的太阳能量抛射还能引起地磁风暴，能够影响宇航员的太空行走，绕地卫星甚至是地面上的通信和电力系统。
