NASA Warns: Possible Infrastructure Disruptions From Solar Flare
March 8, 2012 @ 9:25 am
NASA models using data from the Solar Terrestrial Relations Observatory (STEREO) and the Solar Heliospheric Observatory (SOHO) have now provided more information about the two Coronal Mass Ejections (CME) associated with the two March 6 flares.
Such a CME could result in a severe geomagnetic storm, causing aurora at low latitudes,
with possible disruption to:
- high frequency radio communication
- global positioning systems (GPS)
- power grids.

Northern Lights and electronic disruption on the way after massive solar flareThe biggest space weather storm in five years is heading towards Earth and could disrupt power grids, GPS systems, satellites and airline flights, Nasa has warned. And the Northern Lights could be even more visible than ever over Donegal, if the weather co-operates and skies are clear.
The storm is the result of a massive X5-class solar flare yesterday, according to David Moore of Astronomy Ireland. He explained: “Earth is expected to be hit by the resulting coronal mass ejection (CME) today. This cloud of energised gas is expected to trigger auroral displays all over the world, including Ireland, tonight (Thursday) night and tomorrow (Friday)morning.
“There is a significant chance that the aurora borealis (northern lights) will be visible from Ireland. We suggest keeping an eye on the northern sky throughout Thursday evening and into Friday morning. If it appears, the aurora will have a faint glow and, if the activity is particularly strong, it may have a green and/or red colour. The aurora will most likely be visible just over the northern horizon, but a strong display can result in the aurora being visible all over the sky.
“Ideally it is best to watch the aurorae from a location as far north as possible, but considering on the strength of this particular CME from the Sun, they may be visible further south. We recommend picking anywhere that has a dark sky with a clear northern horizon. This can be a location just outside a town or city, or a dark parkland area.
“If you see the aurora borealis, please let us know what you saw by emailing firstname.lastname@example.org. We will aim to include reports and photographs in an upcoming issue of Astronomy & Space. As geomagnetic storms can affect radio communications, we also welcome reports from amateur radio operators.”
Kenneth McDonagh of the Donegal Weather Channel, says the results of the solar flare are already being seen across the Atlantic. “Shortly after the CME impact, a burst of Northern Lights appeared over the
US-Canadian border. Photographers all over Donegal took some amazing pictures the last time and I know they’ll all be out in force again. Weather permitting, they could get some more extraordinary photos.”

"Prof Cally from Monash University in Australia explains what will happen when the solar storm hits
The Earth is being battered by a storm of charged particles from the Sun, which could disrupt power grids, satellite navigation and plane routes.
This solar storm is the largest in five years - and will bombard the Earth's magnetic field throughout Thursday.
It was triggered by a pair of strong solar flares earlier this week.
The storm was predicted to peak in the afternoon UK time, but experts warn that the Sun's surface is still active and could trigger further storms.
Activity near the Sun's surface rises and falls through an 11-year cycle that is due to peak in 2013 or 2014.
Some solar flares result in what is known as a coronal mass ejection (CME) - the launch of a huge bubble of charged particles hurtling toward the Earth at speeds up to millions of kilometres per hour.
As the Sun's activity has risen in recent months, more such CMEs have occurred."
