TITLE: 08/05 Day Shift: 1430-2330 UTC (0730-1630 PST), all times posted in UTC
STATE of H1: Planned Engineering
INCOMING OPERATOR: Oli
SHIFT SUMMARY:

The main detector activities were JAC measurements, SQZ/ZM4, & input alignment.  A noisy fan for an EY SEI sent Fil & Tony out to swap the power supply (while out there we lost the SUS front end, so that needed to be restored afterword).  Other miscellanea of note:  SEI-ITMx has been at DAMPED since Tues morning (Tony noted); SUS-ITMy has been at MISALIGNED since Monday afternoon; & the TCS CO2 lasers are DOWN.

Another very smoky day (AQI close to 180 at end of shift); fire-wise, only one small fire in Pasco noted in the afternoon.  Had alarms for the LAB1 Dust Alarm a few times during the shift.
