Tues DAY Ops Transition

TITLE: 06/30 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Planned Engineering
OUTGOING OPERATOR: None
CURRENT ENVIRONMENT:
SEI_ENV state: MAINTENANCE
Wind: 13mph Gusts, 7mph 3min avg
Primary useism: 0.01 μm/s
Secondary useism: 0.12 μm/s
QUICK SUMMARY:

Ops workstation (cdsws29) was stuck recovering from morning reboot (hit the on/off button to restore). nuc23 & nuc22 look like they partially came back (will need to log back into them to sort their app windows.

BSC2 SEI work continues (w/ L4C swap & other final checks), FARO measurements may be complete (but FARO remains set-up outside HAM3 just in case). SQZ work continues as well as HAM3 activities and also transfer functions for ITMy.

FOM notes:

For nuc22, I maximized the VAC overview (it's positioning was off only part of window visible after reboot).
- Odd note: wind ndscope had looked when I arrived, but when I glanced up at the window a few min later, the ndscope completely changed (for x-axis it was looking back 80+ days, and y-axis it was looking at -500 to 2000...sort of)
- re-running launch didn't fix it (with a note about ndscope already being open; closed the errant ndscope & rerunning the launch script however did bring back the correct wind...after a few min of waiting for data to appear.
- Will keep an eye on it to see if it randomly changes again.
nuc23 did not allow me to log into it.
nuc30 needed only a few tweaks (but these are for "new" items for non-commissioning/observing, i.e. Reservation System & Trello)
nuc33--I couldn't get the launch.yaml to start the SQZ ndscope for some reason (via several attempts).
