The Looming Threat of a Solar Superstorm

The Department of Homeland Security sponsored a study on the threat of abnormally large Coronal Mass Ejections on our power grid.  They estimated that for only $100 million dollars, our power should be protected from severe geomagnetic storms.

Kapppenman (2010) Worst-Case Scenario for Grid Damage by Geomagnetic Storms

A report prepared for Oak Ridge National Laboratory by John Kappenman an independent consultant, examines the vulnerability of the U.S. electric grid to severe solar storms. The report has generated great interest in government and the public, largely owing to the projected scenario of catastrophic damage, including:

  • More than 300 EHV transformers destroyed
  • 130 million people lacking power for several years until damaged high-voltage transformers are replaced
  • 1-2 trillion dollars of economic loss.

Alone in the Dark: Electromagnetic Pulse and Nuclear Holocaust

Coronal Mass Ejection (CME)

Yesterday’s X5 Flare released a coronal mass ejection (CME) that hit Earth on March 8th around 1100 UT, with little effect.  Nonetheless, every time there’s an X flare, people go apeshit and start searching Google for solar doom links.  Here’s my toss in the pool.  The sun’s been on my mind lately, prompting this cautionary tale of magnetic mayhem.

Have you heard about the Carrington Event?  It was the largest CME ever recorded, dwarfing the puny little flare you just saw in the video above.

May 6, 2008: At 11:18 AM on the cloudless morning of Thursday, September 1, 1859, 33-year-old Richard Carrington—widely acknowledged to be one of England’s foremost solar astronomers—was in his well-appointed private observatory. Just as usual on every sunny day, his telescope was projecting an 11-inch-wide image of the sun on a screen, and Carrington skillfully drew the sunspots he saw.

On that morning, he was capturing the likeness of an enormous group of sunspots. Suddenly, before his eyes, two brilliant beads of blinding white light appeared over the sunspots, intensified rapidly, and became kidney-shaped. Realizing that he was witnessing something unprecedented and “being somewhat flurried by the surprise,” Carrington later wrote, “I hastily ran to call someone to witness the exhibition with me. On returning within 60 seconds, I was mortified to find that it was already much changed and enfeebled.” He and his witness watched the white spots contract to mere pinpoints and disappear.

It was 11:23 AM. Only five minutes had passed.
