UT 23:35 switched to ISAAC due to problem with FORS1
UT 04:43 switched to FORS1
UT 06:20 switched back to ISAAC ... FORS1 did not work again and could not be fixed.
TECHNICAL LOSSES:
FORS1 was given back working while in ISAAC service.
Before switching back to FORS1 (given the dark time and the good seeing) the communication BOB-OT was tested and working ...
However, FORS1 net connection failed again at the end of the first OB (standard) and kept failing despite reboot, reinitalizations, and various checks perfromed by Stephan.

At start of night (in twilight) ISAAC LCU rebooted by itself, therefore no twilight flats could
be taken. No dark time was lost.

The DIT=750-s NDR SW dark did not initially reduce. We resubmitted it and it was fine. The
Technical time 01:10 to investigate pattern seen in acquisition images for
Stiavelli, 71.A-0362(A). This was seen a couple of weeks ago and thought to
be due to the moon. However tonight there is no moon and we see the pattern
again. We think it is due to reflections from Mars, which we can see is
visible through the enclosure slit.

Execution loss: started program 171.D-0004(A), which had to be aborted due to Zenith passage later in the 3h science OB.

Daytime check: seems like shift-and-add did not work for the offset exposures of OB 149621 [prog. 171.D-0004(A)] in the pipeline, possibly because a few stars are saturated (and therefore could not be reliably centroided on).
Daytime calibrations: Calibration check exposure level ~-10. Will monitor it over the next few days.
Lots of ISAAC technical tests during the day.

The Hawaii twilight flats (for odd-even column effect) are getting to be near the limit of 0.98 and are close to the dashed lines on the output produced by "ampl". Have to keep an eye on this. Values shown below. Jonathan.
Lower left quadrant -- Mean value: 19171.2 Odd-Even ratio: 0.9852501
Upper left quadrant -- Mean value: 19780.72 Odd-Even ratio: 0.98594
Upper right quadrant -- Mean value: 18422.76 Odd-Even ratio: 0.9841734
Lower right quadrant -- Mean value: 18424.53 Odd-Even ratio: 0.9840966
The pipeline did not work for the NDR 120-s and 180-s DITT darks readout=NDR. They were both re-submitted and look OK. Other reduced darks fine.
Some FORS1 biases were taken during the afternoon.

ISAAC odd-even column effect numbers OK;
Lower left quadrant -- Mean value: 763.4292 Odd-Even ratio: 0.9997103
Upper left quadrant -- Mean value: 751.1187 Odd-Even ratio: 0.999863
Upper right quadrant -- Mean value: 711.9295 Odd-Even ratio: 0.9964913
Lower right quadrant -- Mean value: 744.6626 Odd-Even ratio: 0.9985118
ISAAC pipeline-reduced data look fine (after they were resubmitted), with the exception of the DCR 1155-s dark; the 3 frames straddle the day number changeover.
