There will be equipment operating on Mt Hopkins Rd at km 12.6, just below the gate, starting on Monday, December 12. Operations will not close the road, but equipment will block the road at times. Please coordinate passage through this area with the construction crew via radio. This work will be ongoing for the entire week.
The heavy equipment operations just below the summit has been completed. Some finishing work with rock and gravel will be done to the parking lot at the summit in the future. We will post that timeline here when we receive it.
Check out a brief, captioned video of the actual aluminization of our primary mirror and hear comments by our staff during the process.
The MMT primary mirror was successfully recoated on September 2, with the coating being uniform across the entire mirror. The measured reflectivity in the blue (at 400nm) is 91.6%, the best achieved at the MMT to date. A minor imperfection is a thin coating along a small area of the south edge (around 6:30) where the glass was shadowed by aluminum foil used to protect the mylar vacuum barrier. Take a look at a photo (you can zoom in), the reflectance plot, and a video of the shot!
