Low-dispersion spectra (range 320-900 nm) obtained July 29.8 UT with the 10-m SALT telescope (+ RSS) show PSN J20342262-3158236 to be a type-II supernova. Comparison with spectra retrieved from the Supernova Spectrum Archive (SUSPECT; http://bruford.nhn.ou.edu/~suspect/index.html) show a good match to the energetic type-IIb 'hypernova' 2003bg approximately 7 days before maximum light (Hamuy et al. 2009, ApJ, 703, 1612).
