Both the UL and LR quads were out and the other two were very high. I wasn't able to get the quad back up until about 20:00 and it took getting the temp up to 199K and on order 15 power cycle attempts. But, it came back! There seemed to be no issue with the vacuum. It had five hours to reach back to 182 K and we had no further problems with it. We had a great night of observing with clear and fabulous seeing all night! UW01 didn't need their twilight time or sky flats and logged out at 12 deg twilight. Did I use my power as a Support Astronomer to do some Venus science for Valentines day? Yes. Yes, I did.
