VENT ACTIVITY STAT mid boot fests
Slow start on vent tasks today - besides the lack of water onsite this morning, and the particularly nasty power outage which are making things not come back up very well, we popped into HAM2 to keep moving on a few of the next steps.  Corey has captured detailed pictures of components and layouts, and Camilla and I have logged all of the LSC and ASC PD serial numbers and cables numbers.  We removed all connections at these PD boxes and Daniel is out making the RF cable meter length measurements.  OPS were realigning all suspensions to a golden DRMI time they chose as a reference for any fall back times.  Jason and Ryan are troubleshooting other PSL items that are misbehaving.

We are gearing up to take a side road on today's plan to look for flashes out of HAM2 to convince ourselves that the PSL PZT and alignment restoration of some suspensions are somewhat correct.
