keanahaki retirement

Jim

IT wants to shut down keanahaki. Need to verify crons can be on different server

• keanahaki = hqcronserver != vm-hqcronserver

• Some tasks should be ported, some can be retired

• Jim will be pinging people to help track down crons

• IT would like to turn off all physical solaris machines

• Solaris containers can still exist (e.g. kapoho/xserver1)

Pier Repair Activities

Jim

Are there tasks to be done while not on-sky w/ K1?

• Shutdown is ~1.5 months

• We have tended to specialize in K1 or K2, some of us will see K2 for the first time in a long time.

• Pier repair is still looking for more people, so AJ and Danny might be pulled, so we could fill in on some instrument tasks.

• PR team is acutely aware that K2 will still be on sky

• Should instruments be covered in plastic to protect them?

• There is a return to science concept that we will need to contribute to

  • e.g. snowing primary? cleaning instruments?

  • HBS health after being off for extended period

• Running the ACs warm as a dehumidifier

  • but particulate counts spike when ACs on

• During test run, it took a week to settle out the pointing. Probably concrete cooling time.

• Josh: need to think about cooling for multiple days before going on sky to equalize thermal masses

• Jim: 2020 had a long shutdown which we can look at for experience

• Exercise dome and shutters during pier repair?

  • Use open shutters for air flow?

• Josh: pull secondary and store in mirror barn? Put First Contact over some optics? Pull or cover tertiary?

• Dome might get warm, does this affect glycol cooling of instruments?

  • Glycol might have to be warmer than usual

  • AO OCAM2k is ok with glycol up to 35C!

• LRIS will be in Cass (nominally)

• Should we pull it (especially if secondary is out)

• Dome clean room will be partially disassembled
