Solar storms originate from sunspots, darker, cooler areas of the surface created by the twisting of its magnetic field. Enormous solar flares mass in scientific parlance leap outward from these sunspots, generating in the process solar wind shockwaves. (Think of a bullet leaving a gun.) And on occasion, the earth sustains a direct hit from these shockwaves. When that happens, the solar winds of supercharged plasma buffet the magnetic shield, interacting with atoms and molecules in the upper reaches of the atmosphere.
All this bumping about produces the transcendent (clouds, flashes, waves, streamers, shafts, etc.) and colors (white, red, violet, pink, green, etc.) we see as northern lights. Two massive solar storms appearing four days apart in the late summer of 1859 gave week the sun touched the its name. The first one reached here Aug. 28, and the second one Sept. 1.
from all over the country, as far south as St. Louis, Louisville and Philadelphia at least, speak of the auroral display as the most brilliant which had been seen for years in their respective noted The Pantagraph in its lengthy account of the first superstorm. And the light show was no less spectacular in Central Illinois. Today, we inhabit a world of visual overstimulation and saturation, and so hard for us to appreciate how these (in the words of The Pantagraph) affected, aesthetically and imaginatively speaking, mid-19th century observers. Although some folks with certain religious proclivities interpreted the aurora borealis (a fancier name for northern lights) as a sign of the End Times, many Americans knew these seemingly fantastical dis plays were natural in origin and were related, somehow and someway, to electricity and magnetism.
Regardless, many of the finely tuned (and attuned) accounts from the 1859 lightshows are impressively sublime. some time the aurora threw out remarkably bright wings along both eastern and western recounted one observer, at the same time the tips of the streamers, where they converged near the zenith glowed with a remarkably intense and fiery Humans have witnessed solar storm-generated aurora borealis since time immemorial, but the storms themselves made little impact on the pre-electrical world. The back-to-back cosmic maelstroms of 1859, though, did play havoc with the Internet of the During geomagnetic solar storms of sufficient strength, telegraph lines and equipment remained even when disconnected from a power source. In the late morning of Sept. 1, amateur English astronomer Richard Carrington was busy sketching an enormous cluster of sunspots when he unwittingly witnessed the origin of the second superstorm a sustained flare emanating from one of the spots, its brightness equal to that of direct This mother of all coronal mass ejections, known today as the Carrington Event, was said to carry the energy of 10 billion billion with a atomic bombs.

A Mr. H. Moore, who lived a few miles outside of Bloomington, watched the grand spectacle with his family. Between 2 and 3 a.m. they witnessed a sky covered with brilliant rays of many colors and of extraordinary beauty, running to a common For Mr.

Lewis, walked outside and, as a test, successfully read newsprint under the The Pan tagraph was a Republican Party newspaper in a highly charged partisan era (the Civil War was less than two years away), so the news story chosen for this special occasion ridiculed U.S. Sen. Stephen Douglas of Illinois, one of the leading Democrats. Midwestern skies have been lit up by periodic aurora borealis since then, such as one particularly strong event on Apr.16- 17, 1882.

This geomagnetic storm rendered useless all telegraph wires from New York to Ogden On the whole, it was a tough day for the Western Union Telegraph Co. In one Chicago office, several operators burned their fingers on disconnected equipment. was the force of the that several wires were burned off entirely, and the switchboard, upon which connections are made, caught fire on several Some readers may recall the geomagnetic solar storm of March 1989 that caused power outages across a large swath of Quebec, leaving millions of residents without power for upwards of nine hours. The aurora borealis from this event could be seen as far south as Texas.
There have been near misses as well. In July 2012, a solar storm packing a punch on par with the two 1859 storms hurtled passed Earth in what was deemed a near miss. A few years ago the National Academy of Sciences studied the potential effects of another Carrington-level event if it were to occur today. Satellites, communication infrastructure and power grids would be at greatest risk. Technologically advanced though we may be, our civilization today is far less resilient and far more precarious than it was in 1859, given our dependence on electricity for well everything.

Damage estimates ran between $1 trillion and $2 trillion trillion with a The appearance of sunspots (and thus solar storms) is cyclical, occurring every 11 years or so. The last solar cycle peaked in 2013. We can breathe easy for now. Yet when it comes to the next Big One, not a question of if, but of when.

PHILADELPHIA (AP) Visitors to the birthplace of America can soon climb aboard a life-size Revolutionary era privateer ship in the heart of the historic district, while staying firmly planted on land.
Builders working with the Museum of the American Revolution in Philadelphia are crafting half of a ship to invite visitors to learn a lesser known story of the Revolution through the lesser known 14-year-old James Forten. The ship will act as one of the primary im mersive exhibits, explore maritime involvement in the Revolution and highlight Forten, a free African-American boy who ser ved on a privateer ship and later became a prominent abolitionist.
