Solar Flares: What Does It Take to Be X-Class? Sun Emits an X-Class Flare On August 9, 2011
ScienceDaily (Aug. 9, 2011) — Solar flares are giant explosions on the sun that send energy, light and high speed particles into space. These flares are often associated with solar magnetic storms known as coronal mass ejections (CMEs). The number of solar flares increases approximately every 11 years, and the sun is currently moving towards another solar maximum, likely in 2013. That means more flares will be coming, some small and some big enough to send their radiation all the way to Earth.

In respect to the hazards of a looming geomagnetic storm I highly recommend to read back to the related blog entries of "our doc" from 2009:

Part one: Space weather storms / Blog March 31st 2009
Part two: A future Space Weather catastrophe / Blog Apr 3rd 2009 [Scroll down to this entry]

Quotation Dr. Jeff Masters from Part two:

"We have the very real possibility that a geomagnetic storms of an intensity that has happened before--and will happen again--could knock out the power to tens of millions of Americans for multiple years. The electrical grids in Europe and northern Asia have similar vulnerabilities, so a huge, years-long global emergency affecting hundreds of millions of people and costing many trillions of dollars might result from a repeat of the 1859 or 1921 geomagnetic storms."

Since I've read those entries, especially the second, I'm aware of our vulnerability amid a "safe" town. And since that I use to have a look at least to spaceweather.com every day.
