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" 22.30 PESSTO classfications (all SN matches with SNID) Object Type Phase redshift Comments 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)

Top three will clash with follow-up targets, hence likely will go for next 5
