2 What is the SSC? The SSC performs the following functions: 1. Collects telemetry and processed data, archives it, and serves it on the web. 2. Receives beacon data from the DSN and NOAA antenna partners, processes it, and makes space weather products available in near real-time. 3. Focal point for science coordination 4. 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.

3 SSC Requirements Process, display, and provide an online browse archive of space weather data for mission lifetime. 2.3 Focal point for E/PO/PAO4.0 Focal point for science coordination3.0 Capture real-time space weather beacon data from NOAA Antenna Partners. 2.2 Capture real-time space weather beacon data from MOC during DSN contacts. 2.1 Space Weather Beacon2.0 Insure that data and software are available to international scientific community (esp., European co-I contingent) and the public. 1.3 Obtain higher level data and analysis software from instrument working archives. 1.2 Obtain Level-0 and Mission Support data for permanent archive.1.1 Archive1.0

6 Software Tasks moc_ingest: Ingest telemetry from MOC – Partially completed, successful test swx_ingest: Ingest SWx telemetry from antenna partners – Draft MOU with NOAA ftp_ingest: Copy files from MOC – Baseline is to use Perl script “mirror” swx_process: Process space weather data – Requires software from instrument teams ins_ingest: Copy files from instrument teams – Use mirror or rsync?

7 Software Tasks (cont.) Stereo_catalog: Baseline is MySQL stereo_bibliography: To be defined Web displays – Space Weather Beacon – Latest Images and Plots – Where is STEREO? – Catalog interface – Planning timeline – SSC health monitor

8 SSC Current Status Amy Skowronek and Marc Despres from the SOHO project are working on programming. – Successful R/T telemetry throughput test with the MOC in January 2004. Joe Hourcle has now joined the team. He's also working on the VSO, and will help us integrate the SSC into the VSO structure. Emilie Drobnes is working on website design. – http://stereo.gsfc.nasa.gov A draft MOU with NOAA is available.

10 Coordinates Recently acquired a sample SPICE kernel for STEREO A&B, together with the IDL interface to the SPICE software. Can derive position in the following coordinate systems (J2000): GEI: Geocentric Equatorial Inertial GEO: Geographic GSE: Geocentric Solar Ecliptic HAE: Heliocentric Aries Ecliptic HEE: Heliocentric Earth Ecliptic HEEQ: Heliocentric Earth Equatorial (Heliographic) Carrington longitude Still researching the following coordinate systems: GSM: Geocentric Solar Magnetospheric SM: Solar Magnetic MAG: Geomagnetic Others?

11 SolarSoft Library The Solar Software Library (SSW or SolarSoft) is a library of software routines used by a number of solar missions. The purpose is to foster software sharing, and combined data analysis. It also simplifies the distribution of software and ancillary (e.g. calibration, catalog) data. The emphasis is on IDL, but other languages can also be included for distribution. For IDL, SolarSoft also simplifies and standardizes the configuration process. Automatic scripts allow the user to keep software and ancillary data up-to-date. http://www.lmsal.com/solarsoft/

12 SolarSoft Tree The basic SolarSoft tree has generic subdirectories, and subdirectories for each misson gen (generic software for all missions) soho stereo … Each mission has the same sub-structure soho gen (generic software for all instruments) cds sumer … Each instrument has several standard subdirectories cds data idl setup (setup scripts)

13 SolarSoft STEREO Have started the process of creating the STEREO part of the SolarSoft library. The library tree has the following directories: gen impact plastic secchi swaves ssc Each instrument team will control their own section of the tree, e.g. via a mirror from the home institution.

14 STEREO Science Operations Plan Have started a draft of the STEREO Science Operations Plan Not a required document, but does collect together information we are required to provide. Will contain information about the science planning process: Overview of planning process and schedule Nominal telemetry and space weather applications Nominal SSR partition allocations Planned Space Weather Beacon data description

15 Planning Process Quarterly SWG meetings Main focus for long-range scientific planning 3-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
