We opened to try and shoot through early on and then closed. We opened again late and tried. We mostly saw cirrus. I noticed a UPS power problem with the Cloud Scanner, and a problem report was submitted. The DIS red chip was looking rather odd and after much head scratching I discovered that the chips were warming. When I went upstairs I found that the quick connect ha not attached properly and when I pushed it in a little further it started filling. I checked the temps and they had not warmed beyond the limit, but were close. They cooled quickly and all was fine thereafter. That fitting is a wonderful convenience but I worry about this sort of thing happening. Is there a more robust model? The guider display stopped displaying guider info shortly before midnight. The IDL interface said "TCC log reset" but I do not know how that happened. I reissued gdrstart and restarted the idl program, but I still could not get a guider display when guiding, around 4:30am.
