Night Report 2014-09-22
Observers: Morgan Fraser, Chris Ashall
TAT: Cosimo Inserra, Richard Scalzo
Data reducers: Nic Walton, Nadia Blagorodnova
Conditions: Thin cirrus cloud with thicker patches across most of sky. Seeing reasonable at start of night ~1.2", but deteriorating over night,
23:47 Start of twilight
23:50 LSQ14fig classification - Ic at z=0.03, post max. Good match to SN 2004aw at ~+5 days.
23:57 End of twilight
00:28 LSQ14fik classification - Ia at z=0.15, around max
01:00 Looks like clouds are clearing, switching to SOFI
01:10 SN 2009ip J band imaging. Reduced frames, target visible (just about)
02:05 TO attempted image analysis, unsuccessful due to clouds
02:20 ASASSN-14gm JHK imaging
02:40 ASASSN-14gm BG+RG spectra
04:55 Telluric standard (solar analog for ASASSN-14gm)
04:00 ASASSN-14ha JHK imaging
04:20 TO focussed telescope
04:30 ASASSN-14ha BG+RG spectra
05:35 Closed due to clouds. OB for ASASSN-14ha spectra was completed, but probably last nod in sequence is useless. Also, no telluric standard was observed.
08:55 Open again
09:00 OGLE-2014-SN-073 classification - Type II at z=0.13! This puts it at an absolute mag of -19.4, with a slow (0.5 mag) rise over at least the last 40 days. Spectrum shows strong, broad Halpha, with a very weak absorption, and clear P-Cygni Hbeta. No obvious narrow lines, still quite blue. Interesting!
09:20 PSNJ01300340-4241487 classification - Very young Type II SN, blue continuum with weak broad Halpha, consistent with redshift of the host ESO244-31.
09:40 Attempted to acquire CSS140914-021317-071932, but sky too bright
