What is a CME?
Think a solar flare!
Coronal Mass Ejection.
CME - Coronal Mass Ejection.
Coronal Mass Ejection which peaks when the dipolar field of the sun is at its weakest point during reversal. The real problem is when the CME’s have reverse polarity to our earth field and are at solar max. Reverse polarity solar max in the sun happens about every 22 years while the decrease in our magnetosphere strength happens about once every 2000 years. Thus, the the perfect storm opportunity only happens on earth about every 44,000 years.
