- If a CME enters interplanetary space, it is sometimes referred to as an interplanetary coronal mass ejection.
- ICMEs are capable of reaching and colliding with Earth's magnetosphere, where they can cause geomagnetic storms, aurorae, and in rare cases damage to electrical power grids.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Coronal mass ejection article was read about 150,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 80 and blocks with 72: each hit it takes is cut by 29 %.
