Solar Storm

Primary Risk impacts:

Satellites:  Communications
GPS:  Navigation
Power Grid:  Power Failure and Failure of the secondary systems that rely upon, including public water, public sewar, public transportation, Public sanitation, etc.

Geomagnetic Disturbances:
 On March 9, a solar flare caused a solar blast aimed directly at earth.   If I’ve interpreted the warnings and timings, within 36 hours we had the Japan Quake/Tsunami.

Probabilities for significant disturbances in Earth’s magnetic field are given for three activity levels: active, minor storm, severe storm   Solar weather forecasted it as a greater the  K7 class event.  To understand alerts for solar weather you can read this information http://www.swpc.noaa.gov/alerts/description.html.

As society becomes more interconnected, and as its systems become more efficient and connected, with risk transferred among them, as noted by James Caverly in an earlier session of the workshop, space weather impacts on electric power grids, satellites, and GPS are going to affect almost every area of our lives. The challenge for society is understanding the true nature of the vulnerability now and in the future.

A direct hit from a CME could trigger a huge geomagnetic storm as incoming particles bounce off the Earth’s geomagnetic field, blacking out radio communications, interfering with GPS navigational systems, in theory even causing power outages.

The China Meteorological Administration reported that the solar flare caused “sudden ionospheric disturbances” in the atmosphere above China and jammed shortwave radio communications in the southern part of the country.

Severe space weather has the potential to pose serious threats to the future North American electric power grid.2 Recently, Metatech Corporation carried out a study under the auspices of the Electromagnetic Pulse Commission and also for the Federal Emergency Management Agency (FEMA) to examine the potential impacts of severe geomagnetic storm events on the U.S. electric power grid. These assessments indicate that severe geomagnetic storms pose a risk for long-term outages to major portions of the North American grid.

    June 21, 2011: In Sept. 1859, on the eve of a below-average1 solar cycle, the sun unleashed one of the most powerful storms in centuries. The underlying flare was so unusual, researchers still aren’t sure how to categorize it. The blast peppered Earth with the most energetic protons in half-a-millennium, induced electrical currents that set telegraph offices on fire, and sparked Northern Lights over Cuba and Hawaii

    Some of the computer models are so sophisticated, they can even predict electrical currents flowing in the soil of Earth when a solar storm strikes. These currents are what do the most damage to power transformers. An experimental project named “Solar Shield” led by Pulkkinen aims to pinpoint transformers in greatest danger of failure during any particular storm.
