2018 Nov 26 - Dec 14

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.

March 1st, 2018

Arriving at Gemini South is the first part of our new instrument "GHOST".  The instrument consists of a unit mounted in the Instrument Support Structure in charge of 'capturing' the light of the telescope.  The spectrograph will be installed in the pierlab connected by over 80 feet (24 m) of cable.

December 2017 GHOST Update

December 1st, 2017

The build of the GHOST Cassegrain unit is nearly complete. In November, Gemini staff participated in weighing and inspecting the fully assembled unit at Australian Astronomical Optics (AAO) at Macquarie University lab in North Ryde, New South Wales. The unit is currently on its way to Chile. In December, Gemini representatives spent a week at the AAO testing the Integral Filed Unit (IFU) positioner and verifying the assembly and operation of the electronics and software of the Cassegrain Unit.
