The Solar and Heliospheric Observatory (SOHO) captured this image of the sun at 5:06 a.m. EDT on Oct 5, 2012 showing a coronal mass ejection (CME) spreading away from the sun toward Earth. Credit: SOHO (ESA & NASA)

Cause and Effect

CAUSE AND EFFECT: When the sun spit out a Coronal Mass Ejection (CME) on Oct. 5, a brilliant aurora appeared three days later over Saskatoon, Saskatchewan, Canada. When Earth-directed, CMEs can affect electronic systems in sate...
