Had a lockloss that seemed to have been caused by an H1IOPSUSEY computer crash. After we figured that this was the issue and started to start the recovery process by restarting the computer, then clearing all of the watchdogs, and bring alignment sliders back to where they should be. No issues recovering there.

Then we noticed that the front StripTool looked odd and the FSS, ISS, and PMC seemed to be having issues. We called Dave to have him look at all this before he went to bed.

The PMC Locked Light showed that it was locked (green) but the HV was basically zero and the PMC Trans camera image was caught on some terrrible mode.  We managed to get the PMC locked again by turning the autolocking on and off and on and off till eventually it locked on a good mode. BUT after we would think that we had it locked nicely, we would watch as the HV would drift away and lose the lock or lose it immediately as we went to engage the FSS. During all of these locks and unlocks the noise eater would start to oscillate and we would end up having to reset it 3 times before we managed to get everything stable. Then we had to fight the ISS from oscillating as well. In the end we won the battle, but feel very battered and confused.

We seemed to have recoved everything except TrendWriter0 which went down in the chaos sometime after the EY crash.
