In 2008 the name of the space weather operation center was changed from Space Environment Center to the Space Weather Prediction Center to emphasize user needs for prediction capability in the space environment. Bogdan noted that the positive side of these moves is that NOAA has incorporated the SWPC within the overall NOAA Weather and Water Goal organization, showing recognition that "weather" includes not only traditional terrestrial weather parameters but also the effects of solar activity (x-rays, coronal mass ejections (CMEs)

Core Mission AND CURRENT CAPABILITIES of the Space Weather Prediction Center The core mission of the SWPC as stated by Bogdan is to: • Assess, survey, analyze, and evaluate the best available data on solar weather; • Evaluate what the needs are, what the research community can bring forward in the way of models and theory, and what real-time data NASA, the European Space Agency (ESA) , and Russian satellites can provide now and in the future on the solar wind, solar particles, and x-rays; • Design, fabricate, test, validate, and install new products and services that meet the needs of the user community; and

For example, the SWPC analyzes and selects the best space environment models developed by many scientists in the research community. Another example is the modeling of Earth's crust in North America around key electrical power transformer locations including the currents induced by past major solar storms.

long-term forecasts of a day or more, the various user communities could take actions to mitigate the effects of impending solar disturbances and minimize the resulting economic impact. Even in the short-term forecasts and warnings category, two areasM-flare and X-flare probabilities and global and regional ionospheric disturbance probabilitiesare coded red.

NERC receives its space weather data from the NOAA SWPC. Ott said that space weather warnings are handled separately at OmniSTAR since terrestrial weather does not affect differential GPS corrections.

Following Bogdan's presentation on the NOAA SWPC, panelists discussed the benefits of receiving high-quality space weather forecasts, as well as the cost of receiving less than accurate or inaccurate (false-alarms) alerts, for operations such as airline polar flights, power company maintenance work and transfers of power between adjacent systems in the grid, and seismic surveys for offshore oil exploration, engineering, and production.
