The big accomplishment today was flipping the shell so that the magnets are now facing up. This video, filmed by Juan Gallardo, shows the last step in the flipping procedure:
After flipping, the back of the mirror was inspected. Everything looks great.
We also attached the ASM unit to the mount ring, which is how the secondary will be attached to the telescope.
Our heat transfer and fluid mechanics experiments continue:
In addition to the main attraction of mirror handling and testing, w-unit and NAS integration work continues. We have tested our X-Y-Z translation stages, installed a new neutral density filter in the VisAO camera, and installed a new gimbal in VisAO. We should actually mount the w-unit in the NAS in the next day or so.
