"Carrington-Class CME Narrowly Misses Earth", video of shocking report presented at the University of Colorado in April 2014 (marrow escape in July 2012)
Science Casts offers a four-minute video “Carrington-Class CME Narrowly Misses Earth”.
The event happened around July 23, 2012 and blasted two successive coronal mass ejections through the same area a few hours apart. Earth had passed through the area a week before. At that time, I was on a trip in West Virginia looking a mountaintop removal, a bit ironic.
The event is covered in “The Blaze” and was mentioned on CNN News late tonight (July 25) but not on local stations. The story is here. The East Coast had just endured the derecho three weeks earlier, on June 29, 2012. But this could have been much more catastrophic. Note the tone of the comments from users.
Large solar storms can fry transformers, and because they are largely manufactured overseas, cannot be put in place here quickly.
A paper on this incident was presented at the University of Colorado in April 2014. It was only the data on a satellite that was hit that told us the severity of the event.
Reuters in the UK published a short article (by John Kemp) on the need to prepare for solar storms today, link here. It is possible for power utilities to take some protective measures if there are several hours notice. These would probably include deliberate blackouts.
The solar storm did appear during a period near the peak of the sunspot cycle when some observers had warned of the possibility of severe solar storms. See my book reviews blog: April 13, 2013 (Michael Maloof), Oct. 20, 2012 (Oak Ridge National Laboratory), Aug 9, 2012 (National Academy of Sciences), June 8, 2012 (NatGeo), Nov. 9, 2010 (Lawrence Joseph).
Predictive Science has said there is a 12% chance of a major solar storm hitting Earth in the next decade, although it isn’t sure what that’s based on.
