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. Following 4 and a half days of inspections, tests, and demonstrations the positioner, electronics, and software were accepted for shipment to Gemini South. The electronics unit is expected to be shipped to Chile by year's end where the team will begin preliminary testing and debugging on the telescope in late January.
