Night Report Page - 20120807

Observers : S. Smartt, C. Inserra (QUB) Flora Cellier-Holzem (LPHNE)
Data analysts on duty : M. Fraser, D. Wright, A. Pastorello

Time shared with Benetti Large Program (BLP) over the first four nights rather than the breakdown of firewalled nights - this was due to RA pressue ranges of targets and having to work around the weather. Data reduced, as much as possible with the PESSTO pipeline

Total time spent BLP : approx 4.5hrs

All reduced data available as tarball (spectra also through WISEREP) - contact Morgan

All times are CST and approximate
19.38 CST : Clear skies, wind has dropped, seeing ~ 1.4", flux standard EG274 with 1.5" and 1.0" slits 
19.40 SN2012P Gr13 2x2000s griz  (BLP). Nice spectra, [OI], [CaII], MgI] Na I P-Cyg, not fully nebular. 
      Very similar to 2008ax at +158 days (Chornock et al.). PESSTOFASTSPEC available.
      griz imaging, image quality around 1.3". Reduced images available.  
21.00 SNHunt133 UBVRi imaging (BLP)
      SNHunt138 VRi imaging (BLP)   IQ ~ 1.3-1.4"

      LSQ12brz                Ia    +9d    0.138    Normal, match to 92A
      LSQ12eeq                stellar like  
      CHASEJ21253403-4016432  Ia    +37d   0.02     normal, match to 03du 
      CHASEJ20032484-5557192  Ia    +40d   0.014    normal, match to 03du 
      LSQ12ecb                stellar like, or late-type galaxy dominated 
      Seeing now 2" 
      Feige 110 and PG2336 (UBVRgriz) 
01.00 SN2009ip UBVRi (BLP)  
      Seeing variable, from 1.3" - 2.4" 
      HDE 269006 (= R71) Gr11+16  and UBVRi (avoided saturation). No sign of [CaII]
      as in CBET 3192, in fact no strong emission lines apart from H-alpha, which is 
      weak. Spectrum is late-type, F-type or cooler.     
02.15 PESSTO classfications 
      Object                 Type  Phase redshift  Comments
      LSQ12ecu               Difficult target, object identified as possible transient has cluster/HII region spectrum
      SNhunt144              Ia    -5d     0.028    Normal, match to 02bo  
      LSQ12dyw               Unclassified, but interesting, very blue continuum, with some broad 
                             features, two weak, narrow emission lines
                             host galaxy in SDSS is not blue, hence continuum is transient dominated 
      LSQ12ecp               Ia    +18     0.077  Normal, match to 03du 
      LSQ12dlf               another unclassified, blue transient. Hostless, no emission or sharp  
                             absorption features. After binning, broad shallow features are apparent. 
                             Unknown redshift. 
     Seeing = 2"
      LSQ12dvr               Stellar - must be some flaw in LSQ data, or the star shows very 
                             high amplitude variations. There is r=17.6 star in SDSS , yet LSQ refs are 
                             blank. Spectrum weird, blue continuum bit NIR excess and molecular 
                             bands in emission. A weirdness I don't care for ! But LSQ team 
                             should check out the data. Edge of chip by the way. 
 **Winds forcing us to observe southern targets only.** 
      SN2012dy               Milena will PI this as a PESSTO target - unusually luminous, energetic 
                             type II. Gr13+UBVRI
      PSN J20032484-555719   Ia    +36d   0.016     normal, match to 94aw 
      HDE 269006 (= R71) Gr11+16  and UBVRi - repeated for 2nd time (looking for rapid variations) (BLP)
