- Evening session (7.4 hrs duration).

- Session operated under semi-automated control, with remote monitoring from indoors computer.

- Ambient Temperature: 0°C minimum

- CCD operation -25°C (at 56% average cooling).  First 256 images at % cooling !

- Main objectives of the session was to continue preparations towards an effective return to imaging
