In Sept. 1859, the sun unleashed a series of solar flares so powerful that telegraph offices caught fire and auroras were seen as far south as Cuba. Known as the Carrington Event, this iconic solar storm is a touchstone for discussions of extreme space weather.

Could it happen again? In a paper published May 10th, researchers from the University of Birmingham use Extreme Value Theory to estimate the average time between “Carrington-like flares.” Their best answer: ~100 years. In other words, we may be overdue for a really big storm. Read the original research here.



The Worsening Cosmic Ray Situation

Re-Blogged From http://www.SpaceWeather.com

[Cosmic Rays (GCRs) were high and Sunspots were low numerous times throughout history, notably during the ‘Maunder Minimum’, ‘Dalton Minimum’, ‘Sporer Minimum’, etc. Those were decades or longer of especially cold climate, like the Little Ice Age that still was around for George Washington and the troops at Valley Forge. Don’t worry about the radiation unless you fly long distances a couple times a week or plan a trip into outer space. You may want to buy a new ski jacket and long Johns though. -Bob]

Cosmic rays are bad–and they’re getting worse. That’s the conclusion of a new paper just published in the research journal Space Weather. The authors, led by Prof. Nathan Schwadron of the University of New Hampshire, show that radiation from deep space is dangerous and intensifying faster than previously predicted.

Eclipse, Global Cooling, Cosmic Rays, etc.

By Dr Tony Phillips – Re-Blogged From http://www.spaceweather.com/

LUNAR ECLIPSE DETECTS GLOBAL COOLING (BUT ONLY A LITTLE): On Sept. 27th, millions of people around the world watched the Moon pass through the shadow of our planet. Most agreed that the lunar eclipse was darker than usual. Little did they know, they were witnessing a sign of global cooling. But only a little.

Atmospheric scientist Richard Keen of the University of Colorado explains: “Lunar eclipses tell us a lot about the transparency of Earth’s atmosphere. When the stratosphere is clogged with volcanic ash and other aerosols, lunar eclipses tend to be dark red. On the other hand, when the stratosphere is relatively clear, lunar eclipses are bright orange.”
