The Antarctic Transient Survey (ATS) reports the detection of SN 2017fbq (=ATS-17A), a likely young Type II Plateau Supernova at RA = 19:33:45.61; Dec = -60:58:02.2 (J2000), located 1".0 east and 0".0 north of the center of the the galaxy 2MASX J19334551-6058022. The Sloan-g magnitude of the transient was 18.5 at UT Jun. 27.86 2017. ATS targets optical transients using a 0.5-m Schmidt telescope (AST3-2) located at Dome A, Antarctica. We obtained an optical spectrum of SN 2017fbq/ATS-17A on UT 2017 Jun 30.46 using the FLOYDS instrument on the 2-m telescope located at Siding Spring Observatory and operated by the Las Cumbres Observatory. Spectral fitting with Superfit (Howell et al. 2005, ApJ 634, 1190) produces a match with the type-IIP supernova SN 2005cs at a redshift of 0.015.
