We report a spectroscopic classification of PSN J20540830-7820035 located at ra=20:54:08.30 dec=-78:20:03.5. A spectrum (range 330-1000 nm) obtained robotically on May 17.70 UT with the FLOYDS spectrograph at "Faulkes Telescope South" at Siding Springs shows it to be a SN Ia near maximum at a redshift of 0.03. Classification was performed via supernova spectrum cross correlation using SNID (Blondin & Tonry, 2007, ApJ, 666, 1024), which yields the best match with SN 2003du (Stanishev et al. 2007 A&A, 469,645) at +3 days.
