September 1st, 1859: The Week the Sun Touched the Earth

Boston telegraph operator, (to Portland telegraph operator): "Please cut off your battery entirely from the line for fifteen minutes."
Portland operator: "Will do so. It is now disconnected."
Boston: "Mine is disconnected, and we are working with the auroral current. How do you receive my writing?"
Portland: "Better than with our batteries on. Current comes and goes gradually."
Boston: "My current is very strong at times, and we can work better without the batteries, as the Aurora seems to neutralize and augment our batteries alternately, making current too strong at times for our relay magnets. Suppose we work without batteries while we are affected by this trouble."
Portland: "Very well. Shall I go ahead with business?"
Boston: "Yes. Go ahead." — Ars Technica covers the story of the Great Auroral Storm of 1859, and the awe it inspired.

The Sun is a Mass of Cyclically Furious Gas

"The sun is waking up from a deep slumber, and in the next few years we expect to see much higher levels of solar activity." Dr. Richard Fisher and other sun-gazing scientists recently discussed the upcoming peak in the 11-year sunspot cycle. Due to the ever-increasing humans' reliance on electrical systems, the storm could leave a multi-billion pound damage bill and "potentially devastating" problems for governments. Constant improvements in satellite designs have assisted in bracing for a solar superstorm, an effort that comes in part by studying the impacts records of activity from past peaks in solar storms. System limits are set based on significant solar storm-triggered events in the past, though the largest magnetic storm on record was before the modern understanding of solar events. The solar storm of 1859, also known as The Carrington Event, when "telegraphs ran on electric air," was experienced around the world. [more inside]

A perfect space storm

A perfect space storm, which happens about every century, like the one that occurred in 1859, could cause "catastrophic social and economic disruptions", according to a new study by the National Academy of Sciences on behalf of NASA. "Potable water distribution affected within several hours; perishable foods and medications lost in 12-24 hours; immediate or eventual loss of heating/air conditioning, sewage disposal, phone service, transportation, fuel resupply and so on," the report states. Outages could take months to fix, the researchers say. Banks might close, and trade with other countries might halt. The next peak in solar activity is expected around 2012.
