Gemini is now accepting proposals for observing time in Semester 2023A. The submission deadline varies with participant. A new version of the Phase I Tool (PIT) has been released to support proposal submissions.
GNIRS has been reinstalled on the telescope and is ready for science use as of July 4th, 2022. All issues with the filter wheels have been fixed and other refurbishment projects have been completed. All slit spectral modes are now available in addition to imaging. The Low Resolution (natural seeing) IFU is installed and is undergoing commissioning. It will be released for science use at a later date. Fabrication of the High Resolution (AO-assisted) IFU is ongoing and is expected to arrive in Hilo at the end of 2022.
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.
In January 2022, itermittent problems began to occur with GNIRS' filter wheel two (FW2). This was found to be due to a faulty ball bearing, which increased drag and friction on the wheel assembly. In order to prevent damage to FW2 or other components internal to GNIRS, a decision was made to avoid FW2 movements entirely. As a result, as of March 15th, 2022, observations were limited to cross dispersed mode only. The faulty ball bearing is to be substituted when GNIRS is warmed up to install the IFU at the end of April 2022.
Gemini is now accepting proposals for observing time in Semester 2022B. The submission deadline varies with participant. A new version of the Phase I Tool (PIT) has been released to support proposal submissions.

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.
Gemini North is accepting proposals for the Fast Turnaround (FT) program. We are not yet accepting proposals for Gemini South. Here, we give information specific to this proposal cycle. Please see the other FT pages - particularly the rules - for general information about the program. FT-specific proposal templates must now be used for all FT proposals; see the "PIT information" section below.
