FLAMINGOS-2 on the Gemini South Telescope

FLAMINGOS-2 was re-installed on the Gemini South telescope on June 11, following replacement of the motor that controls the multi-object spectroscopy (MOS) wheel. Additional concurrent work was done to improve the alignment of the gate valve baffle. The repaired MOS mechanism performed well in lab testing with the instrument in various positions, and it proved to be very stable. The next important step, on-sky commissioning, is scheduled to start the week of June 17.
