Yes it is... (though I do not fully understand it) As dependant as we are on electronics, you would think this kind of report would make the news. Maybe it will after a big one causes us some damage, but not 'till then.
Yes true, but even X class wont do severe damage. But can take down grids as has in past. They added a Y class not to long ago. Makes you wonder why? This is even stronger than X. I think they suspect this new Y class is probable.I think the X class, not the M class, are supposed to be the most dangerous.
(excerpt from here http://www.godlikeproductions.com/forum1/message1017561/pg1The second Carrington Event occurred March 15th 1989 with Quebec, Canada as its epicenter. A wave of ten X-class solar flares set off in rapid succession which was Earth directed knocking out Quebec's largest power grid. 6,000,000.00 people went without power during one of Montreal's worse ice storms. A great number of the population went without power for up to three weeks. The community survived by relying on their neighbors. Homes with a fireplace were the only source of warmth for thousands.
The third Carrington Event was actually a 'near-miss' occurrence. It occurred on November 4th 2003 and is also known as The Halloween Event. The sunspot group had just rotated around the Sun's western limb before exploding. If it had been Earth directed, no one is quite sure what the devastating results would be. This was the largest solar flare ever recorded measuring an X-45. It literally sent NOAA's and the USAF measuring instruments off-the-scale. They had to recalibrate their instruments which will now read solar events beyond X-50.
Thanks for sharing. On the other side...I suspect we well see an uptake in quake clusters or even a larger one somewhere these next couple of days.Update at www.spaceweather.com
They've estimated that an M1, M6 and M9.3 released in the last several days will overtake each other. It should create a large geomagnetic storm, provided they actually continue towards Earth. I wouldn't anticipate a grid-down situation from this, an order of magnitude too small.
