We didn't get to DC readout until after midnight tonight.  There were no huge problems, but several things that it would be helpfull if someone could follow up on:

• Both bounce and roll modes were very rung up on ITMY (preventing DIFF from locking), damping these took us about 1.5 hours.  Was there something particularly rough that happened to that suspension today? 
• Another issue we had was that the alingments of optics hanging from BSC ISIs were drifting a lot in yaw after the end of today's maintence.  Is this related to reisolating the chambers after they were down for several hours?  See the attached screenshot. 
• A third challenge was the FSS oscilating after lockloss, which it has been doing since we inceased the common gain to 20 dB.  I pulled up an old abandoned PSL guardian node, renamed it PSL_FSS.py, and added some logic that should reduce the gain to 0 when it sees an oscillation, and then set it back to 20. This works, it is not on any medm screens or integrated into the ISC_LOCK guardian yet, but if you want to see what its doing or pause it use a terminal to type gaurdmedm PSL_FSS
• While doing this I noticed that the mixer chanel used to decide if the FSS is oscillating is missing from the medm screen.  I looked at adding it, but noticed that the screen is in conflict with the SVN.  If someone has time to resolve the conflict and add the missing channel (which can be found by opening the model) that would be helpfull. 
• The last thing that could be usefull to follow up on is a large glitch at 8:09 UTC, possibly in MC3 or another MC suspension. 

In the end we got to DC  readout, and Evan, Carl and I had a look at the dither alignment for SRM pitch using POP 90 which is now in the ADS matrix.  The script that is in userapps/asc/h1/scripts/ditherSRM.py sets things up, and we could see that we have an error signal that responds to moving SRM and has a zero crossing at a good alignment.  We tried closing the loop but we probably hadn't turned the gain up enough and broke lock for an unknown reason, by this time our alignment had become rather bad and we had a small EQ. 

Since the optics are drifting so much tonight I'm not going to do an alingment now, but if the morning operator could start by doing initial alignment when charge measurements are over that would help us get started tomorow.
