Observers : Morgan Fraser
Support team : Southampton (Mat Smith and others?)
TAT : Joe Anderson, Cosimo Inserra

Start of night: clear sky, but with some haze towards the horizon,  5 m/s wind, 35% humidity
Moon from 02.10 onwards at 75% illumination

End of night: clear sky, no clouds, 1km/s wind, no clouds

Seeing ~<1" throughout night

As this is the brightest night of the subrun, the plan was to start with EFOSC to do the time critical followup target OGLE-073 before the moon was up; then concentrate on SOFI observations for most of the night; before switching back to EFOSC2 at the end of the night for some bright classification targets (when all NIR targets were below airmass 2).

Afternoon calibrations:     EFOSC_bias, EFOSC_FlatSpec, EFOSC_SpecArc

00.04    PSNJ07361576-6930230
             Gr#13 classification - SN Ia

00.20    OGLE-2014-SN-073

             Took 30s acquisition image, used PESSTOEFOSCPHOT to check astrometry.

             Nothing obvious at position of SN, so aborting spectra and taking BVRi imaging instead.

02.44    OGLE-2014-SN-073

             JHK imaging

03.59    PS15ae

             JHK imaging

05.15    PS15ae

             BG spectroscopy

06.48    Hip077338 Telluric std

06.53    PSNJ10544216-2104138

             BG spectroscopy

             Due to elevation, I couldn't get JHK imaging for flux cal. I will get this at the start of tomorrow night.

08.27    HIP090574 Telluric std Not used, double star
             HIP090869 Telluric std

08.40    EG274 flux standard

08.52    Switch back to EFOSC2 (delay as one of the systems froze)

             Skipping image analysis as it would take too long, so PSF is not great. Should be ok for spectra though.

             Gr#13 classification, Ibc at z=0.02?

09.46    LTT7379 standard

09.57    LSQ15st Aborted after acquisition - too bright

             Gr#13 classification

10.02    BR skyflats
