On Nov. 20, 2012, at 7:09 a.m. EST, the sun erupted with a coronal mass ejection or CME. Not to be confused with a solar flare, a CME is a solar phenomenon that can send solar particles into space and can reach Earth one to three days later. When Earth-directed, CMEs can affect electronic systems in satellites and on Earth.

NASA’s Solar Terrestrial Relations Observatory (STEREO) captured this image of a coronal mass ejection on Nov. 20, 2012 at 8:54 a.m. EST, about two hours after it left the sun.

Experimental NASA research models, based on observations from the Solar Terrestrial Relations Observatory (STEREO), show that the Nov. 20 CME left the sun at speeds of 450 miles per second, which is a slow to average speed for CMEs. CMEs can cause a space weather phenomenon called a geomagnetic storm, which occurs when CMEs successfully connect up with the outside of the Earth’s magnetic envelope, the magnetosphere, for an extended period of time. In the past, CMEs of this speed have not usually caused substantial geomagnetic storms. They have caused auroras near the poles but are unlikely to cause disruptions to electrical systems on Earth or interfere with GPS or satellite-based communications systems.

NOAA’s Space Weather Prediction Center (http://swpc.noaa.gov) is the United States government’s official source for space weather forecasts.

On December 11 (tentative), SWPC will introduce two new forecast products titled the 3-Day Forecast and the Forecast Discussion.  These new products will: be available twice a day at 0030 and 1230 UTC; provide space weather information in two separate formats, abbreviated and detailed; and use NOAA Space Weather Scale information.  Examples of these new products are available to familiarize our users at http://www.swpc.noaa.gov/info/3-Day.pdf(the concise, 1-page summary) and http://www.swpc.noaa.gov/info/Discussion.pdf(the in-depth space weather analysis for the technical user).  These two products will supplement the existing product suite and no current products will be discontinued.
