Summary:

Jason worked on the PSL DBB in the morning and various commissioning activities have been going on during the day.  Have had it at DC Read Out for last few hours during the afternoon for ISS work.

If winds pick up, Jim asked Commissioners to give him a call to take the End Station ISIs to a certain state.

H1 Locking Notes:

After a lockloss, there were some FSS issues (resolved by toggling Autolocker).  Kiwamu also noticed an oscillation with the ISS Diffracted Power (on the plot on the ISS medm, the max/min/mean signals are all separated from each other by quite a bit).  To remedy this,

• Click on the "Manual Mode" button in the AUTOLOCK box.  
• Click the "ON" button (which turns off the INTegrator), and wait for oscillation to go away.
• Click the "ON+INT" to reenable the INTegrator.
