The Gemini observing databases will be offline for several hours on Wednesday December 10 while we perform quarterly software updates. During this time the following services will be unavailable:

• Observing Tool synchronizations, file transfers, and non-sidereal target queries
• CADC program key validation
• Phase I Tool guide star probability queries

The new 2015A Observing Tool should be available on Thursday December 11 and will be required to access the observing databases. Please check this site for further announcements.
