Solar Activity and the Risks to Modern Technology

In the middle of our solar system sits a incredibly large nuclear reaction held together by an enormous gravity pull. Many millions of times the mass of the earth, this star emits solar weather that stretches out past the orbit of Pluto. As with weather on earth, the sun's weather can form destructive storms that stretch out from the sun's surface onto the Earth and further into the solar system.

These solar storms are full of particles (protons, electrons, and plasma), radio waves, x-rays and other forms of energy that come from nuclear reactions.

When these storms reach Earth, they can having varying effects on our planet.


What does this have to do with Technology?

Most technology systems, with the exception of the military and some corporate technology, have no built-in resistance to the effects of extreme solar storms.

This means that most of our electronic devices, electric motors and power systems are very vulnerable to solar activity, which may render the devices partially or totally inoperable.


Why Should we be Worried About the Effect on Everyday Technology?

On September 1–2, 1859, the largest recorded geomagnetic storm occurred. Aurorae were seen around the world, most notably over the Caribbean; also noteworthy were those over the Rocky Mountains that were so bright, the glow awoke gold miners, who began preparing breakfast because they thought it was morning. Telegraph systems all over Europe and North America failed.Telegraph pylons threw sparks and telegraph paper spontaneously caught fire.

Some telegraph systems appeared to continue to send and receive messages despite having been disconnected from their power supplies.

This storm was called the Carrington Event and similar strength storms reach the earth every few hundred years.

A storm like the Carrington Event today would cause most of our modern technology to fail within hours. There would be significant electronic damage, power failures, global financial confusion, and disruption to transport and communications.

Without active help and intervention, areas of the earth could experience famines, civil unrest, and wars.



Recent Solar Storms and Increasing Activity Causing Increased Risk

On the 3-5th of August, we had a geomagnetic storm interact with the Earth, causing a G3 storm event to our magnetosphere.

This storm was impressive, but lucky not a threat to most communication and power systems. However, it posed large issues for satellite operators and space operations.



G3 Solar Storm Effects:

Power systems:  voltage corrections may be required, false alarms triggered on some protection devices. Spacecraft operations: surface charging may occur on satellite components, drag may increase on low-Earth-orbit satellites, and corrections may be needed for orientation problems. Other systems: intermittent satellite navigation and low-frequency radio navigation problems may occur, HF radio may be intermittent, and aurora has been seen as low as Illinois and Oregon.

All the definition for the scales of geomagnetic storms, solar radiation storms, and radio blackouts levels are located at the NOAA (National Oceanic and Atmospheric Administration) website. http://www.swpc.noaa.gov/NOAAscales/index.html

NOAA also has a website devoted to monitoring solar storm activity and contains other excellent information on solar activity. http://www.swpc.noaa.gov/

This current solar cycle is showing signs of the beginning of a very active period for solar storms and risks to the earth.

This cycle will continue to increase in activity for several years before subsiding into a calmer part of the cycle.


What to do About the Risks of a Solar Storm?

The issue needs to be treated like an natural event, similar to earthquake risks. As with earthquakes on Earth, we have built better buildings, invest in detection and prediction, educating people and designing government polices to deal with such a disaster.

Just with earthquake risk management, solar storms need to be addressed to minimise the harm to our way of life.

Possible improvements to solar flare storm risks:

• More EM shielding in electronics devices
• Better designed power systems and grids.
• Better warning and forecast of solar storms
• Understand the sun and it's dynamics better.
• Education of people on the topic in a meaningful way.
• Government polices on the issue, risks and reactions to events.

Through education of the public, better understanding of the sun and laws requiring built-in protection for important devices and systems, the world can become resistant to this type of event.

We may never be able to remove the risk of solar storms, but we can minimise its harm to our technology driven world.
