The Sun has been in a bit of a mood lately, spitting out some pretty big flares
(including the second largest one of the current magnetic cycle)
Be sure to scroll down for the photo of the entire Sun, it will change the way you think about it.

Sunspot 1158 is acting up.
It looks like one of the more active sunspots
in the current cycle has erupted with a series of (relatively) rapid-fire solar flares, pointing directly at the Earth. It looks like this evening/tomorrow morning will be prime-time for looking north if you are as far south as, oh maybe Wisconsin or so. You can hear the flares

A perfect space storm
, which happens about every century, like the one that occurred in 1859
, could cause "catastrophic social and economic disruptions", according to a new study by the National Academy of Sciences
on behalf of NASA. "Potable water distribution affected within several hours; perishable foods and medications lost in 12-24 hours; immediate or eventual loss of heating/air conditioning, sewage disposal, phone service, transportation, fuel resupply and so on," the report states. Outages could take months to fix, the researchers say. Banks might close, and trade with other countries might halt. The next peak in solar activity is expected around 2012.
