July 2022 Call for Proposals
Gemini North and South are accepting proposals for the Fast Turnaround (FT) program. Here, we give information specific to this proposal cycle.
GeMS RTC under technical difficulties
The GeMS Real Time Computer is currently experiencing technical difficulties preventing the use of the instrument for the rest of the June 2022 Run. Sincere apologies to our user's community!
Gemini IRAF v1.15 Released - Flamingos 2 MOS Support
Flamingos 2 MOS support is now available in the new full release of Gemini IRAF v1.15. This new version also includes the changes from the recent v1.14 patch, as well as various bug fixes. To install Gemini IRAF v1.15, use conda. If you already have a conda environment (eg. geminiconda) with Gemini IRAF v1.14, activate the environment and install the "iraf.gemini" packages:
> conda activate geminiconda
> conda install iraf.gemini=1.15 --no-update-deps
22B Programs and Schedule Announced!
Gemini 2022B observing programs and schedule have been announced!
Notification emails were sent to successful PIs on June 15, 2022. Please check the schedules page for more information.
Note that the latest version of the Observing Tool is required to access and update 2022B programs.

Capability
IGRINS has no moving parts, and offers near-infrared spectra between 1.45-2.45μm high-resolution (R=50,000). The slit size in the spectral direction is 0.34ʺ, and in the spatial direction is 5ʺ. The plate scale on the imaging detector is ~0.041"/pix, and ~0.091"/pix in the spatial direction of the 2-D spectrum. An example of reduced 2D spectra are shown below.
Data reduction
Since IGRINS is a visiting instrument, the data are ingested into the archive sporadically. It is recommended to use reduced data provided to PIs via emails. These data include the recipes used, final reduced spectra, and telluric calibrations, and are planned to be delivered every two weeks in 2022. For the data format of the delivered products, and for the appropriate acknowledgements please refer to the IGRINS webpage.

2022B OT Released
The 2022B Gemini Observing Tool is now available for download. This update is required to access the Gemini Observing Databases.
The Installation Instructions are linked on the Observing Tool web page, and we recommend that everyone download their programs from the databases rather than import from saved XMLs.
See the the Release Notes for a complete list of changes.
Altair unavailable
The Gemini North Adaptive Optics system, Altair, is currently offline due to a recurrent and intermittent issue with its deformable mirror (DM). Please email your contact scientist if you have any questions or concerns about the potential impact on your program.
GNIRS to be Removed from the Telescope for the IFU Installation
On April 28th, 2022 GNIRS is planned to be removed from the telescope and warmed up in order to perform the GNIRS IFU installation and various refurbishment work, which includes replacement of ball bearings for both filter wheels. It is foreseen to have GNIRS back on sky for the IFU commissioning on July 6th, 2022. During this period, NIRI will replace GNIRS on the telescope.
