The VSO Now

• Standardized API
• Allow searching retrieval of data from
• SOHO, Hinode, TRACE, STEREO, SOLIS, GONG, TON,
  Hanet, Nançay, Big Bear, Mt. Wilson, Mauna Loa,
  etc.
• Same interface for all data
• Allows multiple clients to use VSO
• Web interface IDL Helioviewer HEK Helio

The VSOs role

• Making data available to the solar physics
  community
• Funded via NASAs Solar Data Analysis Center
• Can be more responsive to the needs of the solar
  physics community
• If you want something ask us!
• NASA/GSFC Joe Gurman, Joe Hourclé
• NSO Frank Hill, Igor Suárez-Solá
• SAO Piet Martens, Alisdair Davey

Integration with netDRMS

• Dealing with the flood of SDO data
• Getting the data to the users
• VSO caching nodes will store SDO data
• netDRMS / remote SUMS sites
• Try to reduce the load on Stanford
• Pre-fetching data
• Caching the data in high-demand
• Distributing high-demand data across multiple
  sites
