GNIRS was removed from the telescope to work on filter wheel #2 which had been showing increasing instances of not going into position reliably. The filter wheel datum switches were replaced on both filter mechanisms, a temporary light baffle was removed from wheel #1, and dust was removed from the filters using CO2 snow.

Update November 6th, 2019

F2 is back on sky, fully operational for imaging and long-slit spectroscopy with the OIWFS.

Update September 26th, 2019

Recovery of the cooling was unsuccessful and the cold-heads in F2 must be replaced. This means that the instrument will be unavailable for approximately 4 weeks.

Update September 12th, 2019

The F2 detector has been warming up and has reached the limit for operation. We are working to recover the cooling, but until this is fixed F2 is not available for observations.
