  2. ASI Current Status

  3. Uptime Statistics From RT data (contain communications dropouts)

  4. Managing the aging array Vast majority of our down time is associated with computer related failures and/or issues • Hardware aging is starting to becoming a concern for these instruments. The PCs require parts that, in some cases, are no longer in production. • Based on our observed lifetime of these key components (and the current availability of spares) we are modifying our spare part strategy to maintain the array uptime over the coming years. We are also looking at how to replace components that are no longer available. Cause and Number of PC failures

  7. Alaska/Greenland GBO funding • Starting September 1, 2011 NSF is funding the operation of the Alaska/Greenland GBO for the next 5 years under the name: • Ground-based Imager and Magnetometer Network for Auroral Studies (GIMNAST) • UCB-SSL receives funding for site operations, data collection and recovery, maintenance and repairs • UCLA receives funding for magnetometer maintenance and potential repairs • Use of Alaska/Greenland GBO data collected after September 2011 should be acknowledged to NSF award 1004736
