QUICK SUMMARY:

Quiet morning thus far with technical cleaning team only activity in LVEA. Ran through the morning items from Ops Checksheet (only items of note were: OPO was tripped, so untripped watchdog. Dust Monitor Check looks "OK". Dust monitor alarm at HAM5 (prob due to cleaning), HEPI EX diff pressure is INVALID. Vacuum has lots of (usual?) alarms.)

Morning Meeting Minutes

ETMx work continues with ESD cable, R0 alignment, and TFs Monday.
HAM6
- Ground loop issue (ZM1 is the hold up).
- Fil investigating on the floor, then TJ will run transfer functions
- If TFs bad, this will mean time to fix
- If TFs good, or if problem fixed fast, then we will:
  - Transition LVEA to Laser SAFE
  - HAM6 north door install (Tyler here until 2pm)
- Once door on, can:
  - Roll ISCT6 into place
  - Install light piping on bottom/left viewport (if not pumping, and with a Work Permit!).
  - Install Camera housing (if not pumping, and with a Work Permit!)
- Plan is to start pumping down on Monday.
PSL
- Possible work today (Robert will coordinate)
- PSL System work is good for Mon & Tues (assuming we are down for pumping HAM6).
EY
- Discussion of when we'll open
- Oplev EY work can happen Monday morning
Network is stable, but there is still work going on.
Teamspeak is down (there is workaround via "teamspeak3", supposedly)

Regular TeamSpeak server usage should be possible again.
