  1. STERE The STEREO Science Center William Thompson L-3 Communications NASA Goddard Space Flight Center

  2. STEREO Science Center • We’re the “one-stop shopping” center for the STEREO mission. • We perform the following functions: • Collect telemetry and processed data, archive it, and serve it on the web. • Receive beacon data from the DSN and NOAA antenna partners, process it, and make space weather products available in near real-time. • Focal point for science coordination • Focal point for education and public outreach. • Co-located with the Solar Data Analysis Center (SDAC) at NASA/Goddard.

  3. SSC Organizational Chart The SSC will share personnel with the Solar Data Analysis Center/Virtual Solar Observatory. SDAC/VSO

  5. Virtual Observatories • STEREO will interact both with the Virtual Solar Observatory (VSO), and with the Virtual Heliospheric Observatory (VHO) • The VSO interface will emphasize the imaging data • Sharing personnel between VSO and STEREO • The VHO interface will emphasize the in situ data • Personnel on the STEREO/IMPACT team are also involved in VHO • Anticipate that there will be connections between VSO/VHO and other virtual observatories, e.g. EGSO, VSPO, …

  7. Planning Process • Semi-annual SWG meetings • Main focus for long-range scientific planning • 6-month plan, starting in 1 month • Establishes telemetry (and SSR) allocations • Defines campaigns • Monthly Teleconference • Refines details • Forecast DSN schedule available • Final definition of telemetry (and SSR) allocations • Weekly “Virtual Meeting” • Either teleconference or electronic (e.g. e-mail), depending on requirements. • Conflict-free DSN schedule available Based on SOHO experience

  8. Data Catalog Searches • Have started the process of defining the search forms for the data. • The basic search parameters are date, observatory, sub-instrument, and a few others. • More detailed searches will be added in a second phase.

  9. Event lists & VSO — Search Start with a search menu to narrow down time range and selected properties. SOHO catalog shown as representative test case.

  10. Button goes to search tool for data associated with event. Event lists & VSO — Browse End up with browse tool. Eventually, this will include graphics for each event.

  12. SolarSoft Example: Latest Events • Automatically updated page shows latest solar events. • Shows power of SolarSoft library. • Planning on using a version of this for displaying recent STEREO data on the web. All the STEREO instrument software will be made available as part of SolarSoft http://www.lmsal.com/solarsoft/latest_events/

  13. Where is STEREO? Mockup • Automatically generated using SPICE software. • Data calculated for today’s date in 2007—will reset on January 1st • Updated daily via cron job • Graphical display of STEREO A, B, Sun, and Earth on ecliptic plane • Table shows x,y,z positions of STEREO A and B in several standard coordinate systems.

  14. Instrument Resources Pages • A useful concept is to have resource pages for each instrument. • Similar format for each instrument. • Provides information about file formats, calibration, analysis software, and contact information. • We ask that each STEREO team provide and maintain such a page. • See the SOHO pages at the URL below for examples. http://soho.nascom.nasa.gov/mission/instruments.html

  15. Outreach Activities Websites, lesson plans Posters

  16. A Request • We would like to put the presentations from this meeting on the STEREO website. • Please give your presentations to either myself or Mike Kaiser, or mail them to me at William.Thompson@gsfc.nasa.gov
