abstract = "The Richard F. Caris Mirror Lab at the University of Arizona continues production of 8.4 m lightweight honeycomb segments for the primary mirror of the Giant Magellan Telescope. GMT will have a center segment surrounded by six off-Axis segments, plus an additional off-Axis segment to allow continuous operation as segments are removed for coating. The second off-Axis segment was completed and accepted in 2019. We are currently polishing the optical surface of off-Axis Segment 3. We have completed work on the rear surfaces of Segment 4, the center segment, and offaxis Segment 5. We are assembling the mold for off-Axis Segment 6 with the spin-casting scheduled for March 2021.",
