45m lost to technical problems, otherwise good night.
07/05-08/05 log diary
1hr lost to weather, otherwise good night.
08/05-09/05 log diary
3.5h lost to weather, full dataset for only one field.
09/05-10/05 log diary
35m lost to system failure otherwise very good night: clear, 1.5" seeing.
10/05-11/05 log diary
No time lost, very good night: clear, 1.5" seeing.
11/05-12/05 log diary
5.3h lost to weather, 2 fields observed.
12/05-13/05 log diary
30m lost to system failure, otherwise ok night. New 2dfdr software installed. Quality of d14 data not very good due to instrument problems possibly introducing scattered light and latter frames being observed through high airmass. Object frame d14 #0024 ignored from data analysis. 2df focus drifted and first 50 fibres (CCD 2) of b16, d14 and e02 are a little blended.
13/05-14/05 log diary
Good weather, seeing fairly good. No instrument problems and focus issues resolved.
14/05-15/05 log diary
3 fields observed with 3 hours lost due to cloud. Some of the spectra contaminated by cloud scattered star light.
15/05-16/05 log diary
1 hour lost due to weather. Field b00 equivalent to b01 but with a shift of 1" in their centers. Configuration of field e06, did not downgrade successfully identified objects from e05. Therefore 27 LRGs and 25 QSOs have been reobserved that should have been downgraded.
16/05-17/05 log diary
1.5 hours lost due to cloudy conditions.
17/05-18/05 log diary
A little cloud and scattered moonlight.

Note: increasing halation for first 3 nights, causing bump near

noticeable for some frames on 4th night.
