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
