Gemini North will be closed for scheduled engineering work from September 17-27. During this time we will perform preventative maintenance on the science instruments, the acquisition and guiding system, the primary support system, and the telescope enclosure.
Science Operations Announcements
Update @ 9:20am - The ODB shutdown may start as early as 10:30am HST.
The Gemini North observing database will be offline on Monday September 17 from approximately 11am - 3pm HST for hardware maintenance.
During this time the following services will be unavailable:
- Phase I Tool guide star probability queries
- Observing Tool synchronizations and file transfers (Gemini North programs only)
- Observing Tool non-sidereal target queries (Gemini North programs only)
... and renewed - After the major optical intervention that allowed to get rid of air bubbles in the lens systems, it started delivering science data again.
Gemini North will be closed from Wednesday, August 22 through Saturday, August 25 due to Hurricane Lane. The availability of web services, including Phase-I submission and the Gemini North Observing Database, may be intermittent during this period. This post will be updated as new information becomes available.
Update 2018-Aug-26 @ 11:15am:
Gemini North web services, including Phase-I submission and the Observing Database, are back online, however, Gemini North will remain closed for the night of Sunday, August 26.
GMOS-S came off the telescope on July 18, and after preliminary masurements on the CP instrument lab, the work for the collimator service started this week with the removal of the masks frame and its supporting structure, in order to free the way for the collimator removal.
The Gemini South observing database and related services (e.g. image and guide star searches) are currently offline due to a network equipment failure in La Serena. Repair work is ongoing and service will be restored as soon as possible.
Update: The network connection was restored at around 13:00 local time.
Engineering work on the new Gemini North Laser Guide Star system is taking longer than anticipated and it is not yet clear whether commissioning will take place in Semester 2018B. Therefore, LGS programs have not been included in the 2018B queue and National TACs looked for opportunities to convert LGS+P1 programs to IQ20+P2. If the laser is commissioned within 2018B it will be offered via Fast-Turnaround.
