Geomagnetic Storms Today

A strong Geomagnetic storm to hit the Earth today as a result of a Plasma Cloud or Coronal Mass Ejection from the Sun.  As of this morning it is at G1 level, but NOAA is stating that levels may reach G3 strength. You can see status changes here: http://www.swpc.noaa.gov/

Another issue is that there is a slight chance that an Aurora can be seen as far south as Pennsylvania tonight (3/12).

Here is a Map of where the Aurora is most likely visible tonight.

Solar Storms - Part II

As mentioned in the first segment, solar storms do have an effect on the Earth in many ways.  These storms have an 11 year cycle where the next peak is in 2013. Because of our reliance on technology, these storms also have an impact on our power systems, electronics and communication systems.

Here is a list of critical systems affected;

• GPS
• Power Grids (hospitals & airports most affected)
• Airline communication
• Military & Environmental Satellites

NOAA's SWPC also known as The Space Weather Prediction Center, is located in Boulder Colorado, is our early warning for Space Weather events.  They warn us if there is high solar activity and provides space weather forecasts. 

Solar Storms also cause the effect known as the Aurora Borealis or Northern Lights, the image below shows how solar flare energy ionizes our upper atmosphere and causes this spectacular display.
