The Telescope primary mirror had its yearly hard wash by Gray. This yearly maintenance has extended the period between mirror re-aluminizations as well as keeping the reflectivity high.
This year Gray performed maintenance on our UPS systems. A complete battery change and cleaning was accomplished to guarantee uninterrupted power for the control room and computer systems.
When Gray is not busy fabricating instrument handling fixtures, controller mounts, maintaining power systems and other projects as needed, he can be found performing routine building maintenance. This year the control room floor near the south door had to be completely replaced due to moisture damage over the years. It was found that the door seal was not able to prevent wind driven rain from entering the building. A new seal was designed, installed, and most certainly will be tested this coming winter.
Deck resurfacing was also completed this year. With the snow and ice accumulation from last year’s winter storms the concrete on the east and south side decks took a real beating from shoveling snow and chipping ice. So, a new concrete sealer was applied with traction grit in preparation for winter. Also, this year Gray implemented a wind break on the lower patio to prevent snow drifts from pilling up against the sliding glass door of the living room. Hopefully, this winterization will result in less snow removal.
