The Gemini observing databases will be offline for several hours on Tuesday December 6 while we perform software updates.

During this time the following services will be unavailable:

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

The new 2017A Observing Tool should be available on Wednesday December 7 and will be required to access the observing databases.

Please check this site for further announcements.
