The Gemini observing databases will be offline for several hours on Tuesday, June 2 while we perform software updates.

During this time the following services will be unavailable:

• Observing Tool synchronizations and file transfers
• Phase I Tool guide star probability queries
• Target of Opportunity triggers

The new 2020B Observing Tool will be available after the update and will be required to access the observing databases.

Please check this site for further announcements.
