The Gemini observing databases will be offline for several hours on Wednesday May 30 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 2018B Observing Tool should be available on Thursday May 31 and will be required to access the observing databases.

Please check this site for further announcements.
