Space storms threaten technology

Space storms, sparked by massive eruptions on the sun, pose a large threat to technology on Earth, a US expert has said, following a large solar flare earlier this week.
Thomas Bogdan, the director of the Space Weather Prediction Centre at the National Oceanic and Atmospheric Administration (NOAA), said global positions systems, satellite delivered systems and the power grid are all at risk from solar flares.
Experts experience difficulties predicting space storms, and forecasting such events is "not as good as it needs to be", he added.

Here comes the sun...2011-02-18
Independent online (SA) Chicago - Radiation from the largest solar flare in four years is expected to reach Earth late on Thursday or Friday. Such events can cause radio blackouts and interfere with communication satellites, but the most likely outcome this time will be brilliant Northern Lights displays, US scientists said. NASA scientists on Monday reported an X-class solar flare, the first in more than four years....

Huge storm triggered by solar eruption hits earth2011-02-18
The Hindu WASHINGTON: A powerful solar eruption that triggered a huge geomagnetic storm has disturbed radio communications and could disrupt electrical power grids, radio and satellite communication in the next days, NASA said. A strong wave of charged plasma particles emanating from the Jupiter-sized sun spot, the most powerful seen...

Large solar flare scheduled to hit earth tonight, northern lights expected2011-02-18
The Examiner This past Valentine's day, Monday the 14th saw a large coronal mass ejection erupt from the sun, sending out a Class X solar flare out into space and on towards Earth. This is presumed to be the largest recorded solar flare since the last X level blast which occurred December 5, 2006. On the scale of solar flare strength, X-class flares are the most powerful and are capable of triggering radio...

Huge Solar Eruption Actually Made Astronauts Safer
2011-02-19
Yahoo Daily News As dramatic as it was, the massive solar eruption on Valentine's Day didn't send astronauts aboard the International Space Station scurrying for cover. In fact, oddly, it probably helped lower their overall radiation dose. ‹ the most powerful one in more than four years ‹ sent huge waves of radiation and fast-moving particles streaming toward Earth. The sun has stayed active...

Solar flare radiation hits earth today and tomorrow - what will we experience?
2011-02-17
The Examiner Solar flare radiation is expected to start hitting the earth as of today, and they can be strong enough to interfere with communication systems, navigation satellites and power grids. The effects may also be seen enhancing the Northern Lights, possibly making them visible from the Northern US. Solar flares occur when the sun¹s magnetic fields short circuit, which causes a large amount of radiation...

Solar flare radiation (geomagnetic storms) - behavior, depression, suicide rates
2011-02-18
The Examiner Solar flare radiation plays havoc on human behavior, along with the power grids, communication systems, and navigation satellites. Researchers have found correlations between mood swings, depression and suicides when solar flare radiation is present. Michael Berk of the University of Melbourne has found a link between the suicide rate and increase in the geomagnetic storms, which are triggered by...
