  9. THEMIS Our Role • Assist in design of all aspects of the GBOs (Greffen) • Lead development of ASI control software (Jackel) • Lead development of GBO telemetry & control (Jackel) • Develop data recovery system (Jackel) • Deploy 16 GBOs (Greffen) • Operate 16 GBOs (Greffen) • Real-Time (RT) data retrieval from 16 GBOs (Jackel) • Develop & maintain THEMIS-C website (Spanswick) • Develop scientific data products that are visually appealing (Syrjäsuo) • Integrate RT data into summary & housekeeping web displays (Jackel) • Maintain online archive of entire image data set (Jackel) • Ensure flow through of UCLA magnetometer data (Jackel) • Foster synergy with other Canadian programs • Science (Substorms, Aurora, Machine Vision, ULF Pulsation, etc….) So far, the U Calgary group has been ahead of schedule. We owe Stu Harris a lot for that. Canadian GBO Status Report – December 2004
