We report spectroscopic classification of optical transients 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, targets were observed on 2014 Jul 08, and classifications were made with SNID (Blondin & Tonry, 2007, ApJ, 666, 1024).

Notes:

(1) Clear H and He lines. Consistent with redshift of host PGC 026596 (z=0.010673; HIPASS catalog).

(2) See ATel #6297. Consistent with redshift of host PGC 034856 (z=0.009159; HIPASS catalog).

(3) Also called 02-cx like. Consistent with redshift of host NGC 6806 (z=0.019123; HIPASS catalog).

(4) Consistent with redshift of host PGC 349297 (z=0.053664; Jones et al., 2009, 6dF Galaxy Survey Data Release 3).

(5) Consistent with redshift of 2MASS host (z=0.028326; Huchra et al., 2012, ApJS, 199, 26).

(6) Consistent with redshift of host NGC 418 (z=0.019036; HIPASS catalog).

(7) Very broad lines, difficult to constrain redshift compared to host PGC 009204 (z=0.016164; Theureau et al., 1998, A&AS, 130, 333).
