The last two weeks have not seen any obvious large changes to the facility. Some of the team continue to work on the VIRUS enclosures and their annex. The Annex is where much of the breakers, electronics, fans and junction boxes are located. Other members are sealing/caulking the seams of the enclosure so that when we close it up it will be air tight.

We did have some contractors on site finishing up a few punch list items from our remote thermal area project including a team from Trane came out last week to setup some of their communication hardware and test the glycol temperature control system as far as possible without a load on the system.

We painted some test squares of ultra flat black on the High Resolution Spectrograph (HRS) enclosure in preparation for the beginning of its upgrade.

The mirror team has swapped 4 mirror mirrors in the last two weeks keeping on schedule. They continue to make some improvements to the Strip and Wash room including installing a 2nd hot water hose in strip wash area and adding acid proof shelving.

The at angle tests with the wide field corrector at the University of Arizona are going well. So far all deflections detected are elastic and within specification. We are going to have a final review of the corrector alignment with several external experts in early April to get the final ok for shipping the corrector to the telescope.
