The Space Environment Center (SEC) provides near-real time solar-terrestrial data in a variety of formats including solar images, text reports, data lists, and data plots. Data are available via WWW, anonymous ftp, and a List Server.

The Solar-Terrestrial Physics division of the National Geophysical Data Center (NGDC) archives data in three main disciplines (Geomagnetism, Ionosphere, and Solar & Upper Atmosphere), and two related satellite programs (DMSP and GOES). Much of the data collected by SEC is archived by NGDC and available on various media.

The Lockheed Martin Solar and Astrophysics Laboratory (lmsal) web sites: 72 hour Summaries and Forecast page and Solar Soft: recent images and event time line

The Solar Heliospheric Observatory (SOHO), a cooperative ESA / NASA site, has several pages real-time space weather images: The very latest SOHO images and Current Space Weather, and other general information: SOHO: Exploring the Sun


International Partners

The International Space Environment Services (ISES), formerly the International Ursigram and World Days Service (IUWDS), is a joint service of URSI, IAU and IUGG and is a permanent service of the Federation of Astronomical and Geophysical Data Services (FAGS). ISES has had an important role in coordinating the exchange of solar-terrestrial data between organizations around the world. Centres, known as Regional Warning Centres (RWCs), have the responsibility for collecting data from their geographical areas and exchanging these data through the ISES network. At present, there are ten RWCs located in Beijing (China), Boulder(USA), Moscow(Russia), Brussels (Belgium), New Delhi (India), Ottawa (Canada), Prague (Czech Republic), Tokyo (Japan), Sydney (Australia) and Warsaw (Poland).

The Hiraiso Solar Terrestrial Research Center of the Communications Research Laboratory, Japan, provides a space environment information service providing solar radio spectra, H-alpha images, geomagnetic data, digital ionograms, and a variety of other solar-terrestrial data.

The IPS Radio and Space Services in Sydney, Australia provides real-time space weather data, forecasts and alerts for a wide variety of conditions, including; Solar, Geophysical, HP Propagation, Ionospheric, and TEC.

Solar-Terrestrial Environment Laboratory (STEL), Nagoya University Japan and the STEL GEDAS (Geospace Environment Data Analysis System) -- U.S. mirror site -- Near real-time space weather maps and forecasts of northern hemisphere electric potential and currents in the ionosphere, and other related parameters. Maps utilize ground magnetometer data from a number of observatories, solar wind data from the ACE spacecraft, as well as Weimer's empirical models of electric potential, along with the KRM and rt-AMIE inversion algorithms.
