STATE of H1: Observing at 148Mpc
OUTGOING OPERATOR: Ryan S
CURRENT ENVIRONMENT:
SEI_ENV state: CALM
Wind: 4mph Gusts, 3mph 5min avg
Primary useism: 0.02 μm/s
Secondary useism: 0.18 μm/s
QUICK SUMMARY:
- We've been locked for 30 minutes, in observing since 14:47UTC
- Looks like the lockloss (11:46UTC) in the early morning was from an earthquake (6.4 Philippines)
- CDS/SUS/VAC/Dust looks good
- The MX airhandler has lost connection
As Austin mentioned in his alog nuc26 is not responding over the network. This is the upper camera FOM showing the MC and PR cameras.
Its web image has not updated since Wed 4th 00:08 UTC (Tue 3rd 17:08 PDT). The EDC lost connection to its 12 load_mon EPICS channels at the same time (list shown below)
Ryan says the local display in the control room is updating its images, so we we schedule a reboot of nuc26 at the next target-of-opportunity.

Ryan rebooted nuc26 at 12:10 PDT. The web snapshot now looks good and the EDC has reconnected to its PVs.
