Because of apparent low light levels from the halogen lamp in the calibration unit on the telescope the alignment of the calibration fiber was checked where it is attached to the arm that positions it in front of the fibers. After determining the rotational alignment and limiting the rotational freedom of the calibration fiber the halogen lamp and also the ThAr lamp give normal count rates.

The photon counting head of the new exposure meter can be damaged, and an interlock system was made to switch the meter off when the door is opened and/or the lights are switched on.

The polarimetry upgrade for FIES designed by Nikolai Piskunov & Andrey Dolgopolov from Uppsala University was planned to be installed in December. However, a problem occurred during manufacturing and this has now been postponed till later.
