To facilitate dome flat field and quality control observations a light regulator for the dome light from the control room was installed, but it did not worked well as the light level was very unstable. New electronics was bought, but this still needs to be tested.

Finally useful data was obtained in JHKs in June of a suitable field in very good seeing to define the optical distortion of the WF camera. The analysis of this data is pending.
