  2. What is the SSC? • The SSC performs the following functions • Collects telemetry and processed data, archives it, and serves it on the web. • Receives beacon data from the DSN and NOAA antenna partners, processes it, and makes space weather products available in near real-time. • Focal point for science coordination • Focal point for education and public outreach. • In addition, through interaction with the SOLAR Software Library, the SSC can act as a focal point for software coordination.

  5. SSC Current Status • Amy Skowronek and Marc Despres from the SOHO project are working on programming. • We are currently preparing for a R/T telemetry throughput test with the MOC in January 2004. • Emilie Drobnes is working on website design. • Draft text for the website is currently available. We appreciate any comments from the community. • A draft MOU with NOAA is being prepared. • Current funding looks good for archive and science coordination activities. E/PO and Beacon budget to come from other sources.

  6. SSC website External website (under development) http://stereo.nascom.nasa.gov/ Internal website http://stereo.nascom.nasa.gov/intranet Account: SSC Password: StereoSC

  7. Software tasks • R/T telemetry ingest from MOC • Also ingest via FTP transfer • Antenna partner ingest • Telemetry processing • Data ingest from instrument teams • Data management • Web services

  8. What does the SSC need from the instrument teams? • What formats will the data be in? • SECCHI: FITS • IMPACT: CDF, ASCII, binary flatfile • Are any example data files available (e.g. from earlier missions)? Example telemetry files? • What software will be used to process beacon telemetry? • S/WAVES: IDL • SECCHI: IDL, C • PLASTIC: IDL • IMPACT: C • What software will be used to analyze the data?

  9. What does the SSC need from the instrument teams? • What should appear in the catalog? • What kind of queries should the catalog support? • When will first generation software for processing beacon data be delivered to the SSC? • Each instrument should designate a contact person to discuss software and data flow issues.

  10. What do the instrument teams need from the SSC? • Software coordination, distribution • Instrument team supplied software • Contributed software • Coordinate transformations? SPICE? • Data cataloging, VSO • Search criteria? • Data visualizations? • Science coordination

  11. Operations Working Group Meeting • APL would like to hold a meeting on STEREO operations, to follow up on the meeting last March. • Meeting is a response to questions that APL has been getting recently. • Focus would be on the allocation of resources. • What items should be on the agenda?
