The sun follows a predictable 11 year activity cycle, with the next period of stormy activity expected to begin in 2012-13.
The report by German insurance group Allianz said a high impact solar storm, not easily predicted due to its recorded rarity, could cause blackouts and economic losses of over $1 trillion and that the worst case scenario would be even worse.
