Scientists Predict Big Solar Cycle 131

Posted by Zonk from the batten-down-the-planet dept.
An anonymous reader pointed us at a post on the Physorg blog, which discusses the possibility of an upcoming period of intense solar weather. We've discussed this before, but increasingly the evidence looks like 'Solar Cycle 24' (due to start in 2010 or so) is going to make life interesting here on earth. From the post: "Hathaway explains: 'When a gust of solar wind hits Earth's magnetic field, the impact causes the magnetic field to shake. If it shakes hard enough, we call it a geomagnetic storm.' In the extreme, these storms cause power outages and make compass needles swing in the wrong direction. Auroras are a beautiful side-effect. Hathaway and Wilson looked at records of geomagnetic activity stretching back almost 150 years and noticed something useful:. 'The amount of geomagnetic activity now tells us what the solar cycle is going to be like 6 to 8 years in the future,' says Hathaway."

      Solar Cycle 24 actually starts at solar minimum, which is right about now. The cycle, which is about 11 years long, will peak in about 5 or so years from now, when there will be the most activity on the sun. Although, major flares and CME's can happen anytime, as witnessed by the large flare earlier this month during solar minimum.

      Well, the poles tend to see a lot of magnetic activity, for obvious reasons. Given this, I'd say that if you want the least effects, the equatorial regions are where to be.

      Having said that, I'd like to point out that (due to the scale of these things) they're global events. If a big flare heads our way, it could cause global disruptions. A big flare could effectively disrupt global radio communications, as well as wipe out multiple sattelites. Power grid hits are also a possibility.

      If you are thinking about heading for greener pastures to avoid this thing, my advice to you is not to bother. If you're REALLY worried, get some power filtering equipment/UPSes and a backup generator.

      If you aren't worried...well, I have it on good authority that (if the weather is right) being out on the water during these events can be very spectacular. I had a relative who was out on one of the great lakes during calm weather, and according to him the aurora was spectacular. The smooth water reflected the lights overhead. Personally, I plan on heading north to see the show.
