CME IMPACT: A coronal mass ejection (CME) hit Earth’s magnetic field on Oct. 24th around 1800 UT (2 pm EDT).  The impact strongly compressed our planet’s magnetosphere and may have exposed geosynchronous satellites to solar wind plasma.  Mild to moderate geomagnetic storms are possible in the hours ahead as Earth’s magnetic field continues to reverberate from the hit.  Sky watchers in Scandinavia, Canada, and northern-tier US States should be alert for auroras, especially during the hours around local midnight.  Check http://spaceweather.com for updates.

Solar Energy Has its Downsides Too...

If you are like me, and have experienced the frustration of having your television’s satellite knocked out of place by a big wind storm, perhaps you should worry more about the storms outside the atmosphere instead of inside.

A recent study at the University of California says that low-Earth orbiting satellites might not be designed to handle a solar Megastorm. Now, we are a long way’s away from having to worry about satellites falling from the sky, but the study shows that a Megastorm could make the satellites malfunction much faster than expected, which is bad news for your satellite TV.

Normally, we wouldn’t have to worry about this, but on June 7th, scientists monitored a large solar flare which shot out an unusually large amount of solar material. What was unusual about this flare was that it caught scientists by surprise; no one was expecting the spot to turn into a solar flare.

The simultaneous launch of particles into space is called a ‘coronal mass ejection’ or CME for short. Astrophysicist Phillip Chamberlin of NASA’s Solar Dynamics Observatory was one of the scientists monitoring the event, and says that he had never seen a CME this enormous.

Again, this wouldn’t be a big deal, if the material released from this CME isn’t the same material that could cause satellites to fail, and could even threaten power lines here on Earth.

I think this would be an interesting story to cover, simply because it’s something different, something that not everyone hears about all that often, and could have a significant impact on a lot of people.

I never stopped to think that the sun could be a threat to communication. 20 years ago, well the article speaks to a black out in 1973, we weren’t as nearly exposed to a disruption in our everyday lives as we are today. Specifically as it would relate to communication.

Huge Solar Outburst Captured by Fleet of Spacecraft

NASA’s fleet of spacecraft observing the sun have sent back fascinating and beautiful video from the most recent coronal mass ejection, when a massive burst of matter and magnetic fields shoot out from the star into space.

Four spacecraft recorded the eruption in the extreme ultraviolet band of the electromagnetic spectrum over the course of 2.5 hours. The space agency says CMEs typically eject more than one billion tons of particles at a speed faster than one million miles per hour.
