Science Operations Announcements
Issues with the Acquisition and Guidance unit and secondary mirror control system have been resolved and Gemini North is back on sky. Instrument and telescope checkouts are now complete and queue observations have resumed.
Due to unforeseen issues with the Acquisition and Guiding System the Gemini North engineering shutdown will be extended.
We will update this page as information becomes available.
2021-Oct-04: The issues with the Acquisition and Guiding system have been resolved and on-sky instrument checks have begun!
Due to COVID constraints the planned telescope shutdown at Gemini South has been moved from last two thirds of October to November. The shutdown will start on November 2nd and end November 27th (estimate). The updated telescope schedule can be found here.
Due to the recent spike of COVID-19 cases in Hawai'i the Gemini North engineering shutdown has been extended through the end of the day on Friday, September 17, and the 2021B telescope schedule has been updated accordingly. The MAROON-X visiting instrument block will start as scheduled on Tuesday, September 21, however, the NIFS installation has been postponed until December.
The 2021B Gemini Observing Tool is now available for download. This update is required to access the Gemini Observing Databases.
See the the Release Notes for a complete list of changes.
The Gemini observing databases will be offline for several hours on Tuesday, June 8 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 2021B Observing Tool will be available after the update and will be required to access the observing databases.
A CentOS 7 virtual machine image (OVA file) is now available to facilitate running Astroconda IRAF under MacOS 10.15+, which no longer supports running the necessary 32-bit binaries natively. This comes with Anaconda 2019.10, Gemini IRAF 1.14, DRAGONS 2.1.0 and other packages from Astroconda pre-installed. Users of MacOS 10.14 affected by the Tk bug that causes a desktop session logout when displaying graphics may also want to install this guest distribution as a workaround.
