After a minor fix to its controlling computer, Zorro is back online starting May 31.
April 24th, 2022: GNIRS will be removed from the telescope on April 28th, 2022 and is planned to be unavailable for use until July 6th, 2022 due to the GNIRS IFU installation and refurbishment projects.
May 17th, 2021: The GNIRS IFU installation, originally planned for 2021B, has been postponed until 2022. Therefore, GNIRS will be available for the entire 2021B semester.
After overcoming an issue with the compressors and another with the temperature in the MOS dewar, F2 has been back to queue operations since April 23rd.
A failure in the Zorro PC will make the instrument unavailable until May ~5th.
On Sunday 4th a problem was found with the compressors, affecting the F2 vacuum. The instrument needs to be warmed-up to inspect the issue and therefore will not be available for a week or so.
The blue filter wheel of Zorro has been behaving erratically for past few monhts. This has had only minimal impact on operations, since the great majority of Zorro programs use the same filter. A new filter wheel has arrived recently to Pachon and the replacement will happen in the next few weeks.
As Gemini South resumed nighttime operation, GMOS-S was checked out during last weekend and started operating in queue mode. To be noted is that the CCD1 CTE problem reported on Jan10, 2020 is still present, meaning that programs using the N&S mode for spectroscopy are potentialliy affected, as well as IFU programs. These programs will remain on hold, with the exception of programs where this issue has no impact on the science (e.g. region of interest outside of CCD1)
After the COVID-19 telescope shutdown, F2 will continue off the telescope until further notice, due to pending work on the instrument cold heads.
GPI is not available in semester 20B or later due to being removed from science operations for the GPI 2.0 upgrade and move to Gemini North.
