Please note: This essay is a follow-up from my chronicle on solar storm effects of the 1859 Carrington Event on an industrial era society— forward to the postmodern, microelectronic world of today. To better understand the context of this article, it’s suggested you view my introduction solar storm essay found by selecting the March 2012 archives found on the left side of this page. The National Academy of Sciences (NAS) (funded by the U.S. Congress) produced a landmark report in 2008 entitled “Severe Space Weather Events— Societal Impacts.” It reported how people of the 21st-century depend on advance-technology systems for daily living, The National Academy of Science stated— Electric power grids, GPS navigation, air travel, financial services and emergency radio communications can all be knocked out by intense solar activity. A century-class solar storm, the Academy warned, could cause twenty times more economic damage than Hurricane Katrina.  Some leading solar researchers believe we are now due to a century-class storm.
- July 15, 2012 Aurora Borealis sighting near Everett, WA. This event was caused from an X-class solar storm, which occurred within a week of another X-class storm (X-class being the most severe classification). The 11-year solar cycle is approaching a solar maximum around 2013, this will most likely bring more intense solar storm activity.
Depending on your interpretation of the essay’s title, there is nothing new under the Sun when it comes to our neighboring star’s behavior. Since our Sun left its infancy as a protostar over 4 billion years ago, by triggering a nuclear fusion reaction and entering a main-sequence stage, its solar mechanics have maintained relatively consistent patterns. What has not remained the same is the evolution of life on Earth, in particular, our species’ development of a civilization which now is dependent on a form of energy called electricity.
Reaching back only a few generations into the 20th Century, electricity was considered a luxury—today ordinary life would be impossible without it! And that’s where our beloved Sun comes into the picture, to potentially cast a shadow on our dependency of electricity. Solar storms have been a reoccurring event before time began, but they didn’t affect people outside of providing a fantastic, special effects light-show until a critical event happened in 1859.
In the mid 19th century, while the industrial revolution was near full development, the resource of electric power was first harnessed. Shortly after the electricity was put into use for communication using telegraph technology (a 19th century equivalent of the Internet), is when the Sun revealed a shocking surprise in the most powerful solar storm ever recorded, which was known as the Carrington Event.
The year 1859 was near a peak in the Sun’s 11-year solar cycle, when the Sun’s polarity readies for reversal. Approaching the end sequence of this magnetic shift, brings a solar maximum , which produces violent solar flares and ejects plasma clouds outwards into space. If the flare occurs in a region opposite of Earth, a Coronal Mass Ejection (CME) may send a billion-ton radiation storm towards our planet. Fortunately, the Earth is protected by a robust atmosphere and a magnetic field surrounding the globe, which protects us from most solar winds. However, an intense solar storm with its charged plasma cloud can overwhelm our planet’s protective shields. When an extreme solar storm’s magnetic energy contracts with our planet’s protective magnetic field, it creates geomagnetic induced currents (GICs). GICs are massive amounts of electromagnetic energy which travel through the ground and ocean water, seeking the path of least resistance in power lines, pipelines and rail tracks.
In the extreme solar storm of 1859, the Aurora Borealis was seen near the equator and it was reported people were able to read newspapers outdoors at midnight. Navigational compasses (19th century version of GPS) throughout the world spun-out-of-control due to the flux of electromagnetic energy.
Chronicles of the largest solar and geomagnetic storms in the last 500 years.
1847 — First geomagnetic storm caused by a solar flare, which inadvertently was documented using emerging telegraph technology. Reports were the telegraph system was sending clearer signals by disconnecting its batteries and using the geomagnetic energy from the storm. First published effects caused from geomagnetic storm.
1859 — Becomes known as the Carrington Event; telegraph system becomes inoperable worldwide as some offices are set on fire from supercharge telegraph wire. This is the largest geomagnetic storm in 500 years. Scientists begin documenting future solar storm activity.
1921 — Know as the “Great Storm” worldwide telegraphs and radio signals become inoperable and cables are burned out. This geomagnetic storm is likely to occur approximately 100 years.
1989 — Major solar flare erupts on the surface of the Sun opposite of Earth; a resulting solar storm triggers a massive geomagnetic storm, which overwhelms Quebec’s power grid. As a result of the storm, six million people instantly lose power as a U.S. Northeast and Midwest connecting grids come within seconds of the collapse. As a result, the Canadian government becomes proactive and develops strategies to protect its power grid from future solar storms.
2003 — Know as the “Halloween Storms” this series of geomagnetic storms disrupted GPS, blocked High Frequency (HF) radio and triggered emergency procedures at various nuclear power plants. In Scandinavia and South Africa, section of power grids were hit hard, as many large power transformers were destroyed by the powerful geomagnetic induced currents (GICs).
Chronological Reports and News Accounts of Solar Storms From 1859 to 2003
This is one of the most comprehensive list of solar storm accounts on the web. The site chronicles strange solar storm happenings; such as reports in the early 1960s with TV programs suddenly disappearing and reappearing in other regions. Other unsettling reports include the U.S. being cut off from radio communication from the rest of the world during a geomagnetic storm.

My solar storm articles from February www.bigpictureone.wordpress.com and in the March edition of www.ScienceTechTablet.wordpress.com present a comprehensive picture of how solar flares and solar storms originate, with the potential of producing geomagnetic storms on Earth. If these geomagnetic storms are severe enough, they can threaten our way of life. Some strategies and common sense precautions are offered for civic preparedness in the case of an extreme solar event.
