We report spectroscopic classification of two supernovae with the Wide Field Spectrograph (WiFeS - Dopita et al., 2007, ApSS, 310, 255) on the ANU 2.3m telescope at Siding Spring Observatory, NSW Australia, using the B3000/R3000 gratings (3500-9800 A, 1 A resolution). Discovery and classification information are found in the table below, the targets were observed on 2015 Aug 17, and classifications were made with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).

Notes:

(1) Consistent with redshift of the nearest potential host galaxy GALEXASC J134948.25-065820.9 (z=0.076933, Jones et al. 2009, 6dF Galaxy Survey).

(2) Not consistent with redshift of the nearest potential host galaxy PGC 63183 (distance 0.11 arcmin, z=0.036525, Fairall 1983, MNRAS, 203, 47) but possibly the more distant ESO 184- G 064 (distance 1.99 arcmin, z=0.058424, Donzelli & Pastoriza 1997, ApJS, 111, 181).
