The Gemini observing databases will be offline for several hours on Monday, December 5 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
• Non-sidereal target queries
• Integration Time Calculators
• Target of Opportunity triggers

A new 2023A Observing Tool will be available after the update and will be required to access the observing databases.
