Welcome to the Home page of the STEREO Space Weather Group. The intent is that this be an open web site, where anyone from the scientific community can follow our efforts to prepare computer programs, modeling efforts and research studies in p reparation to use the STEREO observations as a tool for Space Weather. We also invite scientists from outside the SECCHI or STEREO consortia to join in the group's efforts. We describe below the procedure to join the Space Weather group.

There are now two coordinators of the STEREO Space Weather group: David Webb, the SECCHI Space Weather Coordinator and a Co-I on the SECCHI Heliospheric Imager experiment, and Doug Biesecker, of the NOAA Space Environment Center and NOAA's coordinator of the STEREO Beacon data. This site is intended to be the repository of all pertinent details and information related to the STEREO Space Weather efforts. Our activities are closely coordinated with the STEREO Science Center at GSFC where the Beacon data will reside. Our site will be updated as new information and revisions dictate. A general discussion of Space Weather, the role of coronal mass ejections, and the use of the STEREO instruments for space weather is available here [.txt file]. We recently completed a chapter on STEREO Space Weather that will appear in the STEREO Instrument book. The current version is available as a Word.doc

The overall purpose of the Space Weather Group is to help coordinate space weather efforts involving the STEREO mission and its instruments, including that of individual team members, and to help coordinate those efforts that lead to tools and products that can be tested and used before and after the STEREO launch. The STEREO real-time Beacon is a major STEREO effort having Space Weather implications. Other activities of the group include incorporating and interfacing STEREO data and space weather activities with: (1) Imaging and in-situ data from other existing space missions such as ACE, Wind, SOHO, Ulysses, GOES-12 SXI, the Transition Region and Coronal Explorer (TRACE) and Solar Mass Ejection Imager (SMEI), and ground-based observations such as interplanetary scintillation (IPS), optical line and broadband and radio emission, and future missions planned for the STEREO time frame, such as Solar-B, GOES-13 SXI, and the Solar Dynamics Observatory (SDO); (2) The Geospace community to understand the coupling of and responses to CMEs and other transient disturbances by encouraging and participating in space weather campaigns; (3) The Community Coordinated Modeling Center (CCMC) and other simulation and modeling groups to use STEREO data as input to space weather models; (4) The SECCHI 3D Reconstruction and Visualization Team to develop mode ls that have a space weather context; (5) The various virtual observatories that are being developed; (6) The International Heliophysical Year (IHY) program in 2007-08; (7) Meetings and workshops involving space weather; and (8) NASA’s PAO EP/O and other outreach activities.

If you wish to join the Space Weather group and be placed on its e-mail list for future messages,
please send an e-mail message to D. Webb at Note that membership implies being willing to work towards the Space Weather goals of the STEREO mission.

Space Weather Projects

The Space Weather Group consists of teams of scientists at particular institutions and individual scientists. Follow links below to learn about the various efforts underway by these group members.


  • STEREO Instrument Teams:

  • Space Weather Tools and Projects

    Some of the tools and projects currently being developed for use with the STEREO observations for space weather applications are briefly described here [DOC]. These have been grouped into categories of Space Weather Tools, including those for CME Detection and CME-related Features Detection, Space Weather-Enabling Projects, and Data Browsers and Viewers. Each project description contains a title, the names of the main coordinators and their affiliations, and a brief description and goal. Such projects are continually evolving, so this list should be considered only as an indication of the projects that will be available at the start of the mission. Undoubtedly, after launch, and as the STEREO data accumulates, the concepts of how to use these data for space weather purposes will evolve and new projects will be added.
