NOAA TRACKING SPACE WEATHER EVENT
Dec. 13, 2006 — A significant geomagnetic storm is expected to impact the Earth beginning early Thursday afternoon around 1:00 p.m. Eastern time, according to forecasters at the NOAA Space Environment Center in Boulder, Colo. Impacts from this event can cause problems with High Frequency communications, satellite operations and induce currents in power grids.

This geomagnetic storm is the result of a strong radio blackout (R3 on the NOAA Space Weather Scales) with an associated moderate (S2) solar radiation storm that was observed by the NOAA space weather forecasters on Tuesday. Also, the SOHO/LASCO instrument observed a powerful and fast-moving coronal mass ejection directed toward Earth with this activity. LASCO (the Large Angle and Spectrometric Coronagraph) is a set of three "coronagraph" telescopes onboard the SOHO (Solar & Heliospheric Observatory) satellite. This is a NASA and European Space Agency cooperative effort. Observations from this instrument are used by NOAA space weather forecasters.
is a rare occurrence to have a strong event like this so late in the
Solar Cycle,” said NOAA Space Weather Forecaster Larry Combs.
The NOAA Space Environment Center is monitoring current space weather
activity levels and gathering critical real-time space weather data,
using the data for the best forecasts and outlooks. SEC is advising
its customers—such as NASA, commercial airlines and electric power
grid operators—of conditions that directly impact their operation.
The NOAA Space Environment Center is the World Warning Agency of the International Space Environment Service, a consortium of eleven member nations. NOAA space weather forecasters use the data to predict solar and geomagnetic activity and issue worldwide alerts of extreme events. SEC plays a key role in support of the nation’s internal infrastructure in partnership with the Department of Defense and Homeland Security.
In 2007 NOAA, an agency of the U.S. Commerce Department, celebrates 200 years of science and service to the nation. Starting with the establishment of the U.S. Coast and Geodetic Survey in 1807 by Thomas Jefferson much of America's scientific heritage is rooted in NOAA. The agency is dedicated to enhancing economic security and national safety through the prediction and research of weather and climate-related events and information service delivery for transportation, and by providing environmental stewardship of the nation's coastal and marine resources. Through the emerging Global Earth Observation System of Systems (GEOSS), NOAA is working with its federal partners, more than 60 countries and the European Commission to develop a global monitoring network that is as integrated as the planet it observes, predicts and protects.
