Gusty solar winds brushed past the earth's magnetosphere once again last night, producing another awesome showing of northern lights. Kp levels peaked at 5, otherwise considered a G1 (minor) class storm. The high end of the geomagnetic scale is a G5. Such a storm would have the potential to cause widespread power outages, damage transformers, cause navigational issues for aircraft and wildlife, and disrupt radio and satellite communications; but these rarely happen. The only thing damaged by last night's G1 storm was my sleep pattern.
