At the beginning of the night, no connection could be made with the prosilica camera of the guider. With the help of David Rojas, we found that a cable was disconnected, after some tests we were able to establish the connection.

Once connected the prosilica camera we noted that the pointing was lost, we recovered the pointing. I also noted that the image is a little elongated, a bit different to the circled images that we used to have (Could this make guiding worse?).

The exposure meter is not working, I tried to recover it in different ways but it was not possible, so I observed without the help of this tool (please check).

The computer that controls CHIRON was quite slow, at times it was stuck, so I had to restart it. Once rebooted most of the monitoring points were green, but the iodine cells were red, so it was not possible to observe in this configuration (please check)

Due to the technical problems it was not possible to observe the targets: BARNARDS, N Sct 2017, HR6870=HD168733, HD191408 and HD211998.
