From the Harvard Press:




According to NOAA, a G5-class geomagnetic storm can have the following effects:


Power systems: Widespread voltage control problems and protective system problems can occur, some grid systems may experience complete collapse or blackouts. Transformers may experience damage.

Spacecraft operations: May experience extensive surface charging, problems with orientation, uplink/downlink and tracking satellites.

Other systems: Pipeline currents can reach hundreds of amps, HF (high frequency) radio propagation may be impossible in many areas for one to two days, satellite navigation may be degraded for days, low-frequency radio navigation can be out for hours, and aurora has been seen as low as Florida and southern Texas (typically 40° geomagnetic lat.).

The prospect of a major solar storm occurring in the next couple years isn't anything new. NASA has been talking about it for a few years now.

Some folks think it's potentially disastrous, others think it's no worse than other solar maximums we've had in the past. All agree that we are in for a larger-than-normal solar maximum in the next 1-2 years. Most agree it will begin sometime around 2011-2012.

It's already known that solar activity is on a roughly 11-year cycle, including maximum (peak) and minimum (low) solar flare activity. Dr. Dikpati, a NASA scientist, believes that the 11-year cycle is part of another, larger cycle that occurs about every 10 short cycles, sortof a cycle within a cycle. So, every 110 years or so, the larger cycle peaks, causing a huge influx of solar activity. According to him, the next solar maximum will be the peak of the larger cycle. Many other scientists concur.

Back in the late 1800's, a large solar flare hit the U.S. and was powerful enough to melt telegraph wires and cause fires. Imagine if such a flare were to occur today in our "wired" society. In the mid-1990's (can't remember exactly), a good chunk of Canada lost power for about 24 hours due to a large solar flare.

As for the OP, preparing for a solar flare is no different than any other disaster scenario. Solar flares, no matter how powerful, are not particularly dangerous to organic life such as you and me, your dog, plants, etc. It is similar to a massive pulse of electromagnetic energy that can easily blow up power transformers and disrupt all types of electronic communication. Pretend your house suddenly got disconnected from the electrical grid, city water and gas. That's how you prepare.

The "disaster" caused by a massive solar flare is one of social disruption as a result of loss of basic services such as electricity, city water, the Internet, cell phones, radio, etc. It the flare was REALLY powerful, it could potentially heat up anything metal, including the electrical wiring in your house, causing fires and such.
