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 preparation 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 HERE. We recently completed a chapter on STEREO Space Weather that will appear in the STEREO Instrument book. The current version is HERE

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 timeframe, 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 models 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.

Team Members

Email Communication

Individual team members can be reached by email to the above addresses.  A majordomo email list handler is available.   An email by you to with "help" as the message will get you full instructions. There is a "spaceweather" mailing list with the above members.   Team members can distribute a message to all team members by sending the message to the address .   Messages are archived.   A second list, of all SECCHI investigators, is "stereo-all." Some space weather messages of wider interest are sent to this list.

SECCHI Consortium Meetings

There have been 6 SECCHI consortium meetings, most with topics pertinent to space weather or with separate space weather sessions.

  • 1st SECCHI consortium meeting at Easton, MD, November 2000

  • 2nd SECCHI consortium meeting at Abingdon, UK, July 2001

  • 3rd SECCHI consortium meeting at Stanford Univ., Palo Alto, CA, September 10-11, 2002. We had a successful half-day "kickoff" session on Space Weather at this meeting. The Agenda was revised at the meeting in near realtime, and contains links to some of the presentations. These Initial Tasks or Action Items came out of our discussions.

  • 4th SECCHI Consortium Meeting in Brussels, Belgium, April 2003. We had a science session featuring first results from SMEI and HI status and simulation efforts. We also had a SWx session with this agenda and action items. Also more HI talks on their general use in space weather, as a forecast tool, and in the Beacon; forecasting storms and SEPs by Bothmer; developing Beacon software by Wang with these downlink options.

  • 5th SECCHI Consortium Meeting in Oxnard, CA, April 2004. No SWx session but some nice HI talks on science ops and simulations and a Beacon update by Thompson.

  • 6th SECCHI consortium meeting at GMU, Fairfax, VA, October 2005. We had discussions about Beacon operations and a SWx session with discussions on updating the SWx website, what NOAA desires from each STEREO instrument including the Beacon and how they plan to use Beacon data, refining the Tools and Projects list, interfacing STEREO SWx with “outside” groups, campaigns, etc.

STEREO Science Working Group (SWG) Meetings

At the Dec 15-16, 2003 SWG at the Space Sciences Laboratory in Berkeley, CA, there was a session on the Beacon with talks by Biesecker and Matthews.

At the March 22, 2004 SWG at the NOAA Space Environment Center, Boulder Colorado, there was another Beacon talk by Biesecker.

At the December 18, 2004 SWG at the Space Sciences Laboratory in Berkeley, CA, there was another Beacon talk by Biesecker and a SWx Group session led by Biesecker and Webb.

At the SEE STEREO: Science, Education and 3D-Exploration meeting held 2-3 May 2005 at the Hamburg Planetarium, Hamburg, Germany, there was an SWG SWx session led by Biesecker. The agenda, projects, Beacon update, and the Pizzo and Biesecker model were presented by Biesecker. There were other talks by D. Berghmans, M. Pick, C. Russell on Data Browsers for STEREO, E. Robbrecht on CACTus performance on STEREO beacon-data, O. Podladchikova on EUV dimmings M. Kaiser on SWAVES and Space Weather plan, and F. Jansen on the MuSTAnG Space Weather Muon Telescope.

At the March 27-28, 2007 SWG in Greenbelt, MD there was an SWx Group update by Webb.

STEREO Workshops or Related Meetings

The first NASA STEREO workshop was held March 18-20, 2002 in Paris. The workshop website has many items of interest for space weather: First STEREO Workshop

At the December, 2004 Fall AGU Special Session on “Preparing for the Solar STEREO Mission: The 3D, Time-dependent Heliosphere from Models and Observations”, Biesecker and Webb presented a poster on STEREO Space Weather.

At the STEREO/ Solar-B Science Planning Workshop at Turtle Bay, Oahu, Hawaii on November 15-18, 2005, there were talks on the Beacon by Biesecker and a session on combining in-situ and image data led by Webb.

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. 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.
