 The summer shutdown is complete; it was fairly short this year. We accomplished daytime engineering in the first week and used the second week for on-sky engineering. All of the necessary baseline tasks in order to return the telescope to scientific operations were completed. This includes handwashing all the mirrors, a  spring cleaning of the enclosure and instrumentation, greasing/lubricating various moving parts, and vacuum servicing KOSMOS and ARCES. The summer shutdown is complete; it was fairly short this year.

 The 0.5m telescope is working as expected but the cameras (FlareCam and dcam-spare) continue to have problems. There was a loss of vacuum in the CCD canisters, which resulted in frosting/icing within the dewar. Cary serviced dcam-spare and got it back to reliable performance but FlareCam is less reliable and continues to get worse with age. The 0.5m telescope is working as expected but the cameras (FlareCam and dcam-spare) continue to have problems.

-APOLLO had numerous laser and optical alignment issues over the last month and a NASA team came back to the site to work on it. We believe the instrument is now back to working order but there may be additional work to be done to address a recent laser frequency issue.+APOLLO had numerous laser and optical alignment issues over the last month and a NASA team came back to the site to work on it. We believe the instrument is now functional but there may be additional work to be done to address a recently discovered laser frequency issue.
  
 As a reminder, we have a current opening (covered by two different job postings) for the 3.5m chief telescope engineer. We are currently reviewing applications for telescope operator/support astronomer position. As a reminder, we have a current opening (covered by two different job postings) for the 3.5m chief telescope engineer.
