The beginning of the night (until 23:00) was lost due to 8 CCDs that were looking bad early in the day, very likely due to a overheating of MONSOON 3 that was over 34C during last night and then went all the way to 55C in the morning.

Initially these 8 CCDs were showing saturation. It was determined after great job from H. Tirado, J. Rojas and the team down in La Serena, that the controllers for this crate (MONSOON 3) were bad, not the CCDs, so it was better to turn this crate off and try to fix it up next morning, loosing so power to additional 9 CCDs, which required a great effort and dedication from the electronics and technical team. Therefore, CCDs  N13, N12, N11, N19, N19, N18, N17, N16, N24, N23, N22, N21, N28, N27, N26, N31, N30, N29 are not going to show up at all in this night data, covering then 2/3 of its usual area. Alarms were modified as well not to stop observations due to this. Similarly, the focus/donut CCDs were off, so we needed to calculate focus by hand, which for our project is not too critical. The guider CCds were working OK, and everything else did so through the rest of the night.
