Observations:

19:00        Bias, Dome Flats and Arcs. Everything looks good.

23.17        Sunset

23:30        Communication with EFOSC not responding. Rebooting wefosc machine.

23:40        VRi skyflat. Aborted as its too dark.

23.52        LTT745a spectrophotometric standard

23.52        Telescope operator image analysis

00:10        PSNJ01440799-6107074 (classification) --> Ia at max

00.30        Twilight

00.30        SKY_J1353283-5757506 

                  2x1800s Gr#16, high cirrus during observing.   1st spectrum ok - second badly affected by cloud

01.50        LSQ14adi (classification) --> Ia (91T) at max, z=0.11

02.20        LSQ14ahc (classification) --> Ia ~7-9 days pre-max, z~0.05

02.35        LSQ14abd

                 2700s Gr#16 - badly affected by cirrus cloud

                 No internet connect at La Silla from ~02.35  to ~ 06.10

03.26    PSNJ11450358+1958254 - classification --> Ia ~5d pre-max, z~0.007

03.37    LSQ14an - followup - 4x1800s  in Gr13

05.46    Emilia - (re)classification --> 2100s in Gr13 - still featureless spectrum (SNID showing as a Galaxy)

06.35    LSQ14aau - classification -->  IIP at +150d, z ~ 0.05

07.10    LSQ14act - classification --> Ia +3d z=0.057

07.35    PS1-14rf - classification --> from acq image, it has moved - thus asteroid

07.37    LSQ14aca - classification --> from acq image --> classified as asteroid

07.52    PS1-14qj - classification --> Ia +7d after max, z=0.13

08.25    LSQ14ahm - classification --> Ia -7d pre max, z=0.046

08.45    LSQ14ahd - classification --> prob G or K star

09.17    Twilight starts

09.20    LSQ14aby - classification --> asteroid (object has moved - checked the acq image). No minor planet at position though. 

09.30    LSQ14ael - classification  --> acq image only in V --> no object seen - so probably asteroid

09.50    EG274 spectrophotometric standard  - 1 and 1.5 arcsec slits. 

10.00    LSQ14acj - classification  --> acq image only in V --> sky too bright to tell anything. 

10:05   Bias

10:10   Dome flats + Arcs
