Data Sources

ACE Real Time Solar Wind (RTSW) data, Kp index, solar and geophysical forecasts are contributed by the U.S. Department of Commerce, NOAA, Space Environment Center and are available to broad community at http://www.sec.noaa.gov/index.html
Please, read the SEC disclaimer.

The three day Solar-Geophysical Forecast is prepared jointly by the U.S. Dept. of Commerce, NOAA, Space Environment Center and the U.S. Air Force.
The Kp planetary index is prepared by the U.S. Dept. of Commerce, NOAA, Space Environment Laboratory. from preliminary data provided by the contributing stations and the U.S. Geological Survey. Errors and invalid indices are possible.
Solar wind and magnetic field data are provided in the near-real time by the ACE mission. Advanced Composition Explorer (ACE) spacecraft is a NASA mission launched at August 25, 1997 to the orbit around L1 libration point 1.5 million km from Earth and 148.5 million km from the Sun.
Real-Time Solar Wind (RTSW) data from the Advanced Composition Explorer (ACE) spacecraft are made available by the Space Envirnoment Center (SEC) of NOAA as updating data lists and plots. The data are available through the SEC Web site at URL: http://sec.noaa.gov/ace/ACErtsw_home.html
