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.

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!

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.

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.

A new webpage with information on the current status of the GMOS-N detector array is now available here. The webpage provides details on the recent hot column features (see March 10 announcement) and updated recommendations for dither strategies to minimize the impact of the hot columns on science data. Any future updates from the ongoing characterization of the hot columns will be posted on this webpage. 

As of July 2022 the noise problem on CCD2 and CCD1 persists.
