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.

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

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

enhancing the Northern Lights, possibly making them visible from the
Northern US. Solar flares occur when the sun¹s magnetic fields
circuit, which causes a large amount of radiation...

Solar flare radiation (geomagnetic storms) -
depression, suicide rates2011-02-18
The Examiner Solar flare radiation plays havoc on human
behavior, along with the
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
of Melbourne has found a link
between the suicide rate and increase in the geomagnetic storms, which are triggered by...
